How a Solar Cell Works
A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron vacancy or "hole" is created.
Silicon Solar Cell
The majority of photovoltaic modules currently in use consist of silicon solar cells. A traditional silicon solar cell is fabricated from a p-type silicon wafer a few hundred micrometers thick and approximately 100 cm 2 in area. The wafer is lightly doped (e.g., approximately 10 16 cm − 3) and forms what is known as the "base" of the cell may be multicrystalline silicon or single ...
