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.

Much of the current work in solar energy is looking into creating high efficiency cells. So you get the maximum conversion between sunlight and watts produced. The best types of semiconductors are monocrystalline solar cells though this only has a conversion rate of about 30%. You also will get a complete return on your investment within a year or two depending on the size of your solar system.

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.

Traditionally it is the solar silicon that makes solar cells expensive though the cost of a solar cell as decreased dramatically. The main goal with new solar cells is to get the most electricity from the light without having the cost be very high. This is the area that most research is investigating as the highest energy conversion known to date is 35% efficiency.
