Portable solar power supply system

This paper deals with the fabrication of a portable solar system using photovoltaic cells (electricity generated by sunlight). Solar cells are usually made of semiconductor materials, especially silicon. Two layers of semiconductor materials combine with each other. These layers are exposed to sunlight, They absorb photons. By doing so, the electrons are excited and some of them jump from one layer to the next, causing an electric current. This is to protect the environment, prevent the felling of trees and the low cost of this system. The solar energy portal is used in ,space probes,space craft, homes, telecommunications and remote villages that require electricity.
