Even if silicon is actually the market normal semiconductor in the majority of electric devices, including the photovoltaic cells that pv panels utilize to transform sunshine into electricity, it is not really the most effective component on the market. For example, the semiconductor gallium arsenide and related compound semiconductors provide close to two times the effectiveness as silicon in solar units, but they are rarely employed in utility-scale applications because of their high production cost.
 
U. of Illinois. (http://illinois.edu/) professors J. Rogers and X. Li investigated lower-cost methods to manufacture thin films of gallium arsenide that also allowed adaptability in the types of devices they can be integrated into. 
 
If you may minimize substantially the cost of gallium arsenide and some other compound semiconductors, then you might increase their variety of applications.
 
Typically, gallium arsenide is transferred in a single thin layer on a little wafer. Either the preferred device is created specifically on the wafer, or the semiconductor-coated wafer is break up into chips of the desired size. The Illinois group decided to put in multiple layers of the material on a single wafer, producing a layered, “pancake” stack of gallium arsenide thin films.
 
If you grow ten levels in 1 growth, you simply have to load the wafer 1 time. If you do this in ten growths, loading and unloading with temperature ramp-up as well as ramp-down take a lot of time. If you take into account what is required for every growth – the machine, the preparation, the period, the people – the overhead saving this solution provides is a substantial cost decrease.
 
Following the scientists individually peel off the layers and shift them. To accomplish this, the stacks swap layers of aluminum arsenide with the gallium arsenide. Bathing the stacks in a formula of acid and an oxidizing agent dissolves the levels of aluminum arsenide, freeing the single thin sheets of gallium arsenide. A soft stamp-like device selects up the layers, just one at a time from the top down, for shift to one more substrate – glass, plastic or silicon, based on the application. After that the wafer could be used again for one more growth.
 
By performing this it’s possible to make much more material more rapidly and more cost effectively. This process could make bulk quantities of material, as compared to simply the thin single-layer method in which it is typically grown.
 
Freeing the material from the wafer also opens the opportunity of flexible, thin-film electronics made with gallium arsenide or additional high-speed semiconductors. To make devices that could conform but still retain high efficiency, that’s considerable. 
 
In a document shared online May twenty in the journal Nature (http://www.nature.com/), the team describes its techniques and displays three types of units making use of gallium arsenide chips made in multilayer stacks: light devices, high-speed transistors and photo voltaic cells. The authors additionally provide a detailed cost comparison.
 
Another advantage of the multilayer method is the release from area constraints, particularly crucial for photo voltaic cells. As the layers are taken out from the stack, they can be laid out side-by-side on one more substrate in order to produce a much larger surface area, whereas the typical single-layer process limits area to the size of the wafer.
 
For photovoltaics, you want large area coverage to catch as much sunshine as achievable. In an extreme situation we may grow adequate layers to have 10 times the area of the standard.
 
Up coming, the team programs to investigate more potential device applications and additional semiconductor materials that could adapt to multilayer growth.

How Does Solar Power Work?

The basics of solar power:

Solar power is probably the cleanest, most viable form of renewable energy available and it can be used in several forms to help power your house. Many gardens now use solar lights or solar garden water features. The availability and wide use of solar power in gardens shows exactly how versatile it is as a source of energy. The technology and the systems are becoming smaller, more compact and better looking than when they were first created and used. Early examples of solar power systems can be seen in California where, in the 1980s, enough solar power panels were installed to power over 10 million homes.

How do photovoltaic tiles work?

Simply put photovoltaic tiles and other forms of solar energy work by converting some of the energy in sunlight into a clean form of electricity that can be used in our houses. The PV cells consist of a positive and a negative slice of silicon placed under a thin slice of glass. As the protons of the sunlight beat down onto the PV cell they knock the neutrons off the silicon. The negatively charged free neutrons are attracted to the silicon but are trapped by the magnetic field that is formed from the opposing fields. Small wires on the silicon catch these neutrons and when connected in a circuit an electric current is formed.

This reaction gives Direct Current electricity though, and it must be passed through an inverter to be converted into an Alternating Current used in our homes to power any electrical items. Some of the power is lost in this part of the process as the inverter is only around 95% efficient but this is a much greater efficiency than was once available.

The nature of the PV cell means there is little or no maintenance required and there are no moving parts; this means that a typical PV cell can last up to 40 years with no work besides an annual clean.

How can I use them to power my house?

There are several ways to use solar power around the house and not just for powering. You can use it to heat your hot water, heat your pool or even your central heating or if you have plenty of roof space and a reasonable amount of sun you can get a grid tie system; a grid tie system means that not only can you power your entire house but during those times when you create an excess of electricity you can sell it back to the grid. An efficiently solar powered home will be able to reasonably create between 75 and 100% of their own power and because of the grid tie system this means you may not have to pay for electricity ever again.

It can be hard for someone who has never been into the green movement to learn how to purchase and use environment friendly products. However, it is quite easy one you sit down and consider your lifestyle. Living a green lifestyle is about changing what you buy and use to things that will not damage the environment. For those who are just beginning to walk the path towards a sustainable planet, it can be as simple as replacing bleach with a natural alternative that does not leave harmful residues when you use it.

The first step to being environment friendly is to make a list of the top ten items that you use in your home. Do you use a lot of dish soap? Shampoo? Bleach? Write down all of the chemicals and supplies you use and find environment friendly alternatives to those items. This will dramatically alter how much of a environmentally damaging footprint you leave behind in your daily life. You will also want to consider your energy uses. Do you use a lot of electricity on computers? Do you run your stove often? Do you have a top load washer? Making changes to your appliances for energy-star compliant ones will not only lower your electricity bill, but lower the amount of drain you put on your local power grid. Many power companies will offer refunds if you purchase an energy-star compliant appliance.

For those who are serious about environment friendly products and lifestyles, there is even more that you can do. Solar panels are growing extremely popular among those who live in sunny regions. By harnessing the power of the sun in your own home, you can feed electricity back into the power grid, or simply power your own appliances. If your place your solar panels on your roof, you leave no additional environmental footprint, as the space has already been taken up by the foundation of your home.

If you are creative, there are other ways to be environment friendly. Adopt a pet if you can afford to, or support catch and release programs that spay or neuter wild cats and dogs. This may not seem a big deal, but non-native wild animals, such as the cats released or lost by humans, change the ecosystem of the area they now live in. Controlling these populations can prevent further damage to the ecosystem. There are also environment friendly charities that you can support that aim to cleaning up the damage that has already been done to the waterways around the world.

There are many ways that you can help out, from purchasing environment friendly items, charities, and doing your part at home to lower the amount of waste being produced.

Organic Baby Clothes

Organic Baby Clothes

If you want to lower the number of chemicals your baby is exposed to, you should think about looking into organic baby clothes. Organic baby clothes are made from cottons and various other natural fibers to make the materials that your baby’s clothing consists of. Another positive of organic baby clothes is that they do not have any of the anti-wrinkle and harsh chemicals that can cause severe allergies in babies and contribute to the pollution of the planet when disposed of.

There are a couple kinds of organic baby clothes available. Organic, and Fair Trade organic. Fair Trade is a title that many environmentally sensitive people approve of. By making sure that all workers are paid a fair wage, the improvement to the quality of life in third world or developing countries is aided. By purchasing Fair Trade, you give people in these countries the ability to improve their quality of life, better care for their families and provide money for medicine and proper education. Fair Trade is a system that aids workers in their quest for a better life.

Buying organic baby clothes is more expensive than buying regular clothes. There are fewer companies making these organic baby clothes, and the variety in patterns and designs of the clothes is smaller. However, with concerns of the consequences of chemicals, including formaldehyde (which is a known cancer causing agent and irritant), in infants, many parents choose organic baby clothes simply for the peace of mind.

Simply purchasing organic baby clothes is not enough to make certain your baby is not contacted by chemicals and other harmful things. Invest in organic, non-toxic soaps and detergents. This will make sure that your organic baby clothes are not contaminated by any harmful chemicals in the wash. Cotton can carry traces of chemicals for a long period of time.  By preventing the cloth from touching any chemicals to begin with will ensure your baby’s clothes remain chemical free.

When buying organic baby clothes, you need to be certain that the cotton and other fibers are truly organic, and do not have chemicals used in them during the manufacturing process. While the vast majority of organic baby clothes are one hundred percent organic, you should also ensure that no chemicals were used during the sewing process.

Zippers, buttons and other accessories might not actually be organic. However, there are manufacturers of purely organic accessories that do work together with those who make organic baby clothes. This can vary from one brand of organic baby clothes to another, so it is important to do your homework.

Organic baby clothes can be bought on the internet or through local specialty stores. If you are handy, you can buy organic materials yourself and make your own baby clothes.  That is potentially the best way to ensure everything that touches your baby is organic and chemical free.

Green Products

Knowing the right way to choose gree products can take all of the guess work out of what was once an unknown proceedure. Most people are concerned about the environment these days and the consequences that human conduct will have on future generations. Due to this, there is a push to own and use only green products. These items are safe for the natural world, and did not cause harm to the natural world when they were made. However, there are some things that you need to know and understand about green products in order to have a proper understanding of what they are and how to choose them.

To begin with, when a business claims their green products do not harm the natural world, they do not mean that no damage was done at all. What they mean is that there is no lasting harm to the natural world. In other words, the production of their green products does not lower the sustainability of the planet for future generations. Most products in one way or another cause some form of damage to the natural world when being made. This can be in the form of pollution from the transportation of the product from factory to store, or in the form of the land used when building the processing and manufacturing plants required for their creation.

The most common labeling of green products states that the product will not cause damage to the environment when it is disposed of. These types of green products are the most popular as they help maintain a sustainable environment and are much easier to get rid of when you are finished with them.

Some green products are also designed to help make items in your home safer for yourself and your children. A good example of this is the devices that take chlorine out of your drinking water, baths and showers. Chlorine is a cleansing agent, removing harmful substances from the water. However, chlorine is also an irritant. It can dry out hair and skin and precipitate various reactions to those with sensitive skin or bodies susceptible to chlorine. By taking out the chlorine from the water, you can enjoy better baths and better tasting drinking water.

Other green products that can help support the environment include organic shampoos, organic soaps, non-toxic toothpastes, and recycled paper products. By adjusting and being aware of the decisions you make in the grocery store, you can make a large impact in how much damage you do to the natural world. If consumers support green products, more will be produced. If more are produced, they will become more common, less expensive and widely used. This will result in a much greater sustainability of the planet for our children and their childrens children.

Relying on Solar Power For Home Use – Advantages and Disadvantages

June 20, 2009 by admin  
Filed under Solar Home

Comments Off

Many people are looking for ways to decrease their bills with the economy getting worse all the time. One way you can decrease your power bill is to install solar panels for your home. Personal solar panels can be a great way to help the environment and at the same time save you money over time. So what are the main advantages and disadvantages to relying on solar power for your home?

Lets consider the advantages of solar power first. Solar power is a unlimited and renewable source of energy. The sun shines every day with tons of solar radiation ending up wasted since a large portion of the energy produced by the sun is not absorbed. Another great advantage solar energy has over fossil fuels is that it emits no CO2. That means no harm to the environment. Any alternative energy source that reduces our dependence on oil and coal is a great thing.

Solar cells don’t need very much in the way of maintenance and last for years because they don’t have any moving parts. Also solar panels are completely silent – they will produce energy for many years without ever making a single sound. Solar cells are also quite simple and easy to install. Commercially made solar panels are actually quite efficient as well.

So now that you know the advantages of solar power, you might be wondering what are the disadvantages? Well for starters, creating solar power can be expensive. It costs a pretty penny to produce solar panels because he technology in creating solar cells has not yet matured. It has seem some pretty significant advances recently but solar power wont be cost effective for at least a few more years.

Another disadvantage of solar energy is that solar power cannot be created at night. This means a solar power generator is only producing electricity half of the day. There are ways to combat this such as storing up energy is batteries for consumption later but if that is used up, more can’t be generated until the next morning.

So while there are many advantages to solar power the disadvantages of it will not be able to be overcome yet for a few more years. Still solar energy should not be discounted. It can still be a great way to combat global warming by reducing CO2 emissions. Also it can be a great way to save money on your energy bill over time. As technology improves, solar power will become more viable and a more efficient way to provide power.

Comments Off

One of the most commonly asked questions in the field of energy and electricity management is how does solar energy work. We have to consider that the sun is one of the most plentiful forms of power that we could utilize, but only a handful of people are relying on it.

Since the sun touches the entire planet in cycles of 12 hours, energy could be easily derived to support many of our every day functions. It is such a waste of money since people have disregarded this as a regular, renewable source of power and electricity.

Here are some of the significant scientific processes involved in solar energy conversion and utilization:

- Solar energy contains a number of molecules including electrons and protons which are essential in the life cycles found in plants, animals, weather and biological processes. In the case of utilizing solar power as an energy source, electrons are the ones which are used for electricity.

- Electrons can be gathered and manipulated with the use of materials which can be purchased at any utilities store. Basically, sunlight can be quickly transformed to electricity due to the fact that the molecule it contains is full of energy.

- Electrons move at a very fast rate, which is an advantage. It can be isolated easily due to its fast movement.

- The solar plates coupled with a photovoltaic cell can isolate the electrons so they can be utilized as an energy source.

- The first stage is the absorption of the molecules through the solar plates. The solar plates have the ability to assemble concentrated electrons and channel them to the semiconductor plates.

- Once the electrons have been gathered, their transport to the battery is the next stage. The electrons go through a series of filters known as the converter and semiconductor wires and plates.

- This is to assure that the electricity produced is composed of pure electrons. Having protons mixed in the procedure would only cause power interruption. The protons are absorbed and disposed through an alternate exhaust, which excretes the molecules away from the battery connection.

- The final process to utilize electricity is the storage in the batteries. Usually, a set of 10 batteries are used to allow a large amount of electricity to be stored. At this point, what are left are pure electrons, which are considered the source for electrical power that is used by electrical gadgets and appliances.

The process of converting sun light into electrical energy is a very innovative process, which could save people a lot of money. Power plants and fossil fuels require a lot of resources to process and cause massive pollution. This is very harmful in the long-term consideration of the condition of the planet.

Experts are continually formulating new scientific strategies on how to utilize the sun as an energy source. Scientific institutions regarding energy manipulation have a lot of guidelines regarding the question how does solar energy work.

Do it yourself solar power? Discover how, in one weekend, you can reduce your electric bill and give you bragging rights in your neighborhood. Learn which do it yourself guides are easiest to follow and give you the most bang for your buck.
