Solar cell or Photo voltaic cell (PVC) is device which directly convert solar energy to D.C power.
This cell made of semiconductor that generate electricity when it absorb light. Gallium arsenide is the another solar cell material.Solar cell made of gallium ,arsenide can retain efficiency at much higher temperature,than cell made of silicon.The best known application of photo voltaic cell for electrical power generation. In space craft silicon solar is the most highly developed type.
Various Advantages of solar cell are:
a. Need little maintenance.
b. life is longer.
c. Do not cause environmental pollution.
d.Easy to fabricate.
e. Energy source for solar cell is unlimited.
Disadvantages are:
a.Cost of production of electrical power very high compare to other.
b. Output electrical power varies with the time and weather , generally power produce in day.
c. Solar cell produce small amount of power compare to the other.
