Energy from the sun is by far the largest energy source available on the earth: the amount of solar energy reaching the surface of the earth annually(3.9 *〖10〗^24J) is about ten thousand times more than the global primary energydemand and more than all available energy sources on the earth .Furthermore, it is inexhaustible and clean source of energy, which is essential in the globally prevailing circumstances: Environmental issues with concerns on global warming, green house effects, depletion of natural reserves like fossil fuels, natural gas, coal, etc. is motivating research to invest in technologies that can harvest energy from renewable energy sources like wind, solar, tidal waves, etc. Of these, the solar energy with irradiance levels of up to 1kW/m2 is abundant and photovoltaic power is a prime candidate for electrical energy generation, population is increasing and environmental problems are growing ever more serious. One of the most potential and versatile methods for utilizing this vast energy source is its direct conversion into electrical energy with photovoltaic (PV) devices.…show more content…
