Abstract

Cdte/Cds thin film solar cell is one of the most promising materials for device applications. It has a high performance efficiency,high emission coefficient and its band gap is close to the optimum value for efficient solar energy conversion. Efficient multilayer thin film solar cell performance requires optimum parameters of each layer. Since the cell thickness and radiation coefficients are the most influential parameters on the efficiency of any solar multilayer in this paper we use transfer matrix method to calculate the thickness and triple radiative properties of emission, reflection and transmission of silicon, indium tin oxide,zinc oxide,cadmium sulfide, cadmium telluride, copper and silver multilayer structure. The derivation results optimized with genetic algorithm at 0.6526 micrometer wavelength with an angle of incident 45° at 25°C.The results show that by changing in the wavelength emission and reflection coefficient  can be improved up to 8% and 16%  and by changing in angle of incident emission and reflection coefficient  can be improved up to 14% and 36%. It was seen that for all cases transmission coefficient is approximately zero and other of triple coefficients behave in the form of sinusoidal curves oppositely.
