Solar energy in the world

P-V Cell Function: -
When a photon particle hits the n layer above the P-V cell, the photon particle is absorbed by the silicon, so the photon particle gives strength to the n level electrons. These electrons are mainly located in the valence band. When the electrons receive energy from the photon, the electrons cross the energy gap and enter the conduction band. Thus, the free electrons reside independently. Then when the circuit is filled, these electrons flow through the circuit, thus generating electricity.

The benefits of using Solar Energy are as follows:- 
1   Own a private power system
2   No bills are required
3   Lasts 20 years
4   No load-shedding
5   No fuel costs
6   Not easily wasted
7   Can be placed anywhere in the country
8   The environment is good
9   Does not harm the environment
10 Low cost.

Other forms of fuels for energy conversion

In today's civilization, the need for energy or energy is immense. As technology advances, the dependence on electricity is increasing. To meet this demand, we are generating electricity by burning various fuels like petrol, coal, gas, etc. But because these fuels are limited, scientists have been researching new inventions, which have led to the identification of new cells as fuel cells or fuel cells. A fuel cell is a type of chemical reaction that produces an electric current. German scientist Frederick Scobien first conceived the idea of ​​a fuel cell in 1838. Later in February 1839, the famed British physicist William Robert Grove implemented the idea of ​​generating electricity through a fuel cell. For the first time in 1958, the use of commercial fuel cells began. The use of fuel cells began in the NASA spacecraft in 1960. Fuel cells are produced by chemical reactions that satisfy the water thirst of the innovators. It is not useful when the chemical element of the battery is exhausted, but it can be used every time the chemical element of the fuel cell is supplied. That is why it is called portable fuel.

Fuel Cell Concepts: -
A fuel cell is an electrochemical cell where DC current is generated by the reaction of hydrogen and oxygen, and water and heat are generated as a byproduct.
