Effect of Humidity on the Efficiency of Solar Cell (photovoltaic)

Abstract: Out of 100 % energy coming from sun approximately 30 % of the energy is either reflected back or is absorbed by clouds, oceans and land masses. In cities where the humidity is more, like Karachi Mumbai, Malaga, Hamburg and Los Angles where in average humidity ranges in (40-78 %), results in a minimal layer of water vapor at the front solar cell directly facing Sun. The Solar energy which actually strikes the solar cell is subjected to loss in absorption/reflection of energy. There have been approximate losses of about 15-30 % of the energy in addition to 30%. One of the effects that we found out after our experimental analysis was of the humidity that it brings down the utilization of solar energy approximately to 55-60 % from just 70 % approximately of utilized energy
