The comfort of human life vastly depends on the ease of availability of energy. Renewable energy sources are at par from their counterparts as far as cost factor is concerned. Solar energy can be converted to electrical energy using a solar cell which is a device based on photovoltaic effect. It has got a wide range of applications ranging from calculators, watches etc. to remote area power stations, earth orbiting satellites, space probes etc. The materials used in solar cells show preferential absorption of the wavelengths of solar spectrum that reach the earth surface. Since the process cost of silicon wafer based solar cells is very high, attempts are being continuously made to find an alternative. In the present study the performance of various solar cells based on perovskite materials having comparatively lower photo-catalytic activity, stability against photo-corrosion and stable photochemical properties has been discussed. These systems have already reached conversion efficiencies exceeding 20%. More than one technique used for fabrication and the role of the size of the nanoparticles in the film and film thickness has been studied.
