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.
In a PV array, the solar cell is regarded as the key component [46]. Semiconductor materials are used to design the solar cells, which use the PV effect to transform solar energy into electrical energy [46, 47]. To perform its duty satisfactorily, it needs to have the maximum PCE feasible [45].
