School of science, Hefei University of Technology, Hefei 230009, China ; 2. Shanghai Space Power Institute, Shanghai 200233, ChinaAbstract:According to the theory of optical film, a computer program was designed. The IR cut-off filter of A｜[1.05（LMHML）]（LMHML）6[1.15（LMHML）]1.15L｜G G on the top surface of encapsulation glass and the UV cut-off filter of G｜H/2LH/2｜ on the rear surface of encapsulation glass for silicon solar cell were obtained. Plotted transmission curves for IR and UV cut-off filter showed that： the IR cut-off filter and UV cut-off filter both have good selective transmission for incidence light. Most of the light（ λ〉1l20nm） is reflected by IR cut-off filter, most of light （λ 〈 350nm） is reflected by UV cut-off filter, and all of the light （350nm 〈 λ〈 1120nm） is almost transmitted to the solar cell. In the range between 350nm and 1120nm, the weighted transmission coefficient of light is 97.49%.[著者文摘]
