Solar cell is a semiconductor junction device which is use to convert the incid
radiation energy into electrical energy. defined as under.
Definition: Solar cell is a photoelectric cell, whose electrical characteristics sm
as current, voltage or resistance vary when exposed to light.
Solar cell is also optosensitive voltage generator or photovoltac a
generated is proportional to the intensity of incident radiation. A com
example of solar cell is a silicon solar cell which converts radiant energy o
into electrical energy.
Materials: The materials used for solar cell are gallium arsenide, int
arsenide, indium arsenide and cadmium sulphide.
materials are selenium and silicon.
