Abstract :
This work Investigates the feasibility of using a solar spectral radiation model SMARTS2 to estimate the global solar irradiance and assess the influence of spectral light content on the conversion efficiency of the CdTe, CIGS and microcrystalline solar cells due to the shift in spectral composition. The variation of the common performance indicators such as short circuit current, fill factor, open circuit voltage, and efficiency are shown and discussed for each month. The results show that the seasonal variations in the solar spectrum affect the different materials to different extent. For the CdTe, CIGS and microcrystalline cells the maximum efficiency is obtained in the summer months, however the lower efficiency is obtained during winter.
