Solar energy is radiant light and heat from the Sun. It is a free, clean energy and inexhaustible resource. Solar cell is consisting of two types of semiconductors, namely p-type and n-type materials. When sunlight is absorbed by these materials, the solar energy knocks electrons loose from their atoms, allowing the electrons to flow through the material to produce electricity.
