EfficiencyEfficiency is defined as the ratio of energy output

from the solar cell to input energy from the sun.

The efficiency of a solar cell is determined as the

fraction of incident power which is converted toelectricity and is defined as:

Pin=F*Ip*A=6.678*100*244*10^-11=21.57watt

n(neta)=Pout/pin*100=.198/21.57*100=91.8%

Application

Rural electrification: The provision of electricity to

rural areas derives important social and economic

benefits to remote communities throughout the

world like power supply to remote houses,electrification of the health care facilities, irrigation

and water supply and treatment.

Ocean navigation aids: Many lighthouses are now

powered by solar cells. Telecommunication systems: radio transceivers on

mountain tops are often solar powered.
