Abstract: The world depends on sources of energy for electrification and utilization. The conventional energy sources are a non-renewable in nature and getting depleted day by day. The renewable energy sources such as solar and wind are available infinite in nature. Even- though the extraction of energy from renewable energy is costlier, maintenance cost is low and energy can be extracted for a long time without any demand. Solar power extraction is pollution free and cost effective energy sources compared to other energy sources. The Sun creates its energy through thermonuclear process which converts 650,000,000 tons of hydrogen into helium. This process creates heat and electromagnetic radiation, later streams into the atmosphere in all direction. In these radiations only 57% hits the earth surface which 1.6×1018 units of energy from sun. The energy of photon and wavelength of light is inversely proportional to each other. The sunlight in ground level consists of 44% visible light, 3% ultraviolet light and the remaining is infrared light. Since the atmosphere blocks 77% of the sun’s UV-radiation, only Infrared light radiation hits earth. Photovoltaic cells absorbs high frequency radiations such as ultra violet and visible lights which converts radiation into electricity whereas the infrared radiation is a low frequency radiation is generally converted to heat or thermal radiation. In normal silicon solar cell, IR radiations just pass through the photovoltaic cell that converts into heat and hence affect the efficiency.
