Solar Cell Diagram (Photovoltaic cell): Know Working Principle
There are two types of semiconductors used in solar cells: n-type and p-type. The lower layer of the solar panel is doped with fewer electrons and more holes, making it a p-type semiconductor. On the other hand, the top layer is doped in the opposite way, with slightly more electrons, also known as n-type semiconductor silicon.
Principles of Solar Energy Generation – Energy and environment
If a wire is connected from the cathode at n-type silicon to an anode of p-type silicon, electrons flow through the wire. The electron is attracted to the positive charge of p-type material and travels through the external load creating flow of electric current. The vicinity of a p-n junction when exposed to light is shown in the Fig.4.

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.
