摘　　要：通过理论分析、仿真和实验测试,确定了影响晶体硅太阳电池太阳吸收率的主要因素,其中铝背反射器、硅片表面形貌、硼扩散对太阳吸收率的影响较为显著,硅片厚度、磷扩散的影响相对较低。采用有陷光结构的高效硅电池能明显降低电池的太阳吸收率,滤光玻璃盖片叠层电池太阳吸收率比普通玻璃盖片叠层电池低16.2%。Through theoretical analysis,simulation and experimental test,the main factors affecting the crystal silicon solar cell solar absorptance were determined.And the effect of aluminum reflector,silicon surface morphology,boron diffusion on solar absorption rate was significant.The influence of wafer thickness,phosphorus diffusion was relatively low.The solar absorption rate could be significantly reduced by using high efficiency silicon solar cells with a light trapping structure.The solar absorption rate of the filter glass cover sheet was 16.2% lower than that of the common glass cover PERL stack.
