The Importance Of Solar Silicon In Photovoltaic Cells
February 25, 2010
The main transformer in a solar cell requires solar silicon in order to work properly. A solar energy will collect light or sunshine and convert this into electricity by producing an electric current. Solar energy is renewable and you can use solar panels to supplement your current electrical use. This saves you a lot of money while using an environmentally friendly power source.
Many people will use solar power to supplement their current electrical needs and most new houses and buildings are automatically integrating solar power into the power systems. Using solar energy is a great way to save a lot of money as well as helping the environment. Homes and businesses that use solar power also get large tax rebates.
The latest research and development in to solar cells is in creating high efficiency solar cells. The current solar cells do not produce as much power as they can so cells are being produced that can convert more and more energy.
The best types of surfaces for high efficiency are monocrystalline silicon. In general you can expect to get your original investment back within one to two years.
The solar silicon is what creates the electric field and three different things can occur when the light hits the silicon; the light can be absorbed in to the silicon, it can be reflected off the silicon or it can pass through the silicon. What is desired is for the light to be absorbed by the silicon. The light causes electrons to move and be channeled which produces a current and electric field.
This energy gradient occurs because of the two different silicon layers found in a semiconductor. These layers tend to be called a p-n junction as a layer of p type silicon which has a high concentration of electrons is in contact with a layer of n type with a low concentration of electrons. As the electrons move between the two layers you generate electricity.
