Complete Guide About Solar Cell
Construction of a Solar Cell. A solar cell is made up of multiple materials that collaborate to produce power.. A semiconductor material, commonly silicon, is the initial layer of a solar cell''s construction.The p-n junction, which separates the two differently doped regions of the material, is formed by impurities doping this layer.

Silicon Wafer
In electronics, a wafer (also called a slice or substrate) is a thin slice of semiconductor, such as a crystalline silicon (c-Si), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells. The wafer serves as the substrate for microelectronic devices built in and upon the wafer.
