Photovoltaic (PV) Cell: Structure & Working Principle

A silicon photovoltaic (PV) cell converts the energy of sunlight directly into electricity—a process called the photovoltaic effect—by using a thin layer or wafer of silicon that has been doped to create a PN junction. The depth and distribution of impurity atoms can be controlled very precisely during the doping process.

How a Solar Cell Works

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 …
