  represent content about Solar Cell, How Does it Work?. 

From construction of solar cell, Doping N-layer and P-layer, influence of depletion region or P-N junction.

Solar Cell construction (00:23)

Solar cell is constructed from this parts N-layer, P-layer, Metallic conductors, Module encapsulate, glass cover, Back Sheet.

Role of Solar cell is to produce electric current from solar energy.

N-layer (01:32)

In a process called "doping", impurity atoms are placed in very pure silicon to change the electrical characteristics of the crystal. Phosphorus can replace some of the silicon atoms in the crystal and when this happens the phosphorus atom is called a dopant

atom.

P-layer (02:43)

Boron, with five protons and five electrons, can also substitute in a silicon crystal where

a silicon atom would normally reside. Because a boron atom has only three electrons

available in its bonding shell, only three covalent bonds can be formed between a boron

atom and the silicon atoms in a crystal.

P-N Junction (05:36)

P-N Junction or depletion region is made when  N-layer and P-layer connect together, and when electrons try to fill holes in entire volume. Most Solar cells are large area of P-N junction
