Solar Cell ConStruCtion Solar Cell ConStruCtion
Solar Cell Principle • Solar cell is a device or a structure that converts the solar energy i.e. the energy obtained from the sun, directly into the electrical energy. • The basic principle behind the function of solar cell is based on photovoltaic effect.
Solar Cell Current • Solar cell is also termed as photo galvanic cell. • The electricity supplied by the solar cell is DC electricity. • DC current is same like provided by batteries but a little bit different in the sense the battery is providing constant voltage.
Definition of Solar Cell Definition of Solar Cell In another way of defining the solar cell it is a solid state electrical device that converts energy of light directly into electricity by Photoelectric Effect.
Construction of Solar Cell • Mainly Solar cell is constructed using the crystalline Silicon that consists of a n-type semiconductor. • This is the first or upper layer also known as emitter layer. • The second layer is p-type semiconductor layer known as base layer. • Both the layers are sandwiched and hence there is formation of p-n junction between them. • The surface is coated with anti-reflection coating to avoid the loss of incident light energy due to reflection.
