Understanding the Composition of a Solar Cell

Solar radiation is converted into direct current electricity by a photovoltaic cell, which is a semiconductor device. Since the sun is generally the source of radiation, they are often called solar cells. Individual PV cells serve as the building blocks for modules, which in turn serve as the building blocks for arrays and complete PV systems

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.
