Solar Cell

Photovoltaic cell, also known as PV or solar cell, is created from semiconductor material such as silicon. The process of solar conversion is as below:

1) when light strikes the solar cell, a specific portion or "band" of the light wave is absorbed by the material;

2) that solar energy causes the semiconductor material to release electrons;

3)the semiconductor material is positioned within an electrical field by using negatively or positively charged silicon(n-type and p-type), so that all electrons set "free" from the material are forced to flow-generating electrical current.?
