Solar energy is pollution free and is abundantly available. Solar energy utilizes sunlight to give heat, light,electricity, etc. for domestic and industrial uses. With the alarming reduction of major energy resources such as coal, petroleum and gas, combined with the environmental deprivation caused by the process of harnessing these energy sources, it has become a necessity to capitalize renewable energy resources that would power the future energy needs adequately without degrading the environment through greenhouse gas release. Commercially available solar cells have efficiencies in the range 10-20%. Although recent breakthrough in the technology of solar cells shows significant improvement but the fact that the maximum solar cell efficiency still falls in the less than 20% range shows there is huge room for improvement. Mathematical models of the three types of solar cells (Monocrystalline, Polycrystalline and Thin film) were simulated using MATLAB. The values of irradiance and Temperature were varied and the effect of these in the efficiency of the solar cell was seen. Then an accumulative effect was seen which shows the effect of wind on the efficiency of solar cell. The data of different cities of Balochistan was also simulated and the results were seen. It was seen in this research that the temperature and irradiance affect the efficiency of the solar cell a lot and that the thin film solar cell is the most temperature tolerant solar cell.
