摘　　要：运用时域有限差分方法,研究了光栅减反层结构对太阳能电池光电转换效率及储能效果的影响。具体从光栅形状、高度以及光栅表面金属薄膜厚度出发。结果表明经光栅减反层优化表面结构的太阳能电池的光电转换效率显著增大,储能效果大大得到提升。尤其是三角形光栅太阳能电池。随着镀层厚度的增加,储能效果增加,但当薄膜厚度过厚时,储能效果反而降低。A numerical investigation of the effect of grating antireflective layer structure on the photoelectric conversion efficiency of solar cells was carried out by the finite-difference time-domain method.The influence of grating shape,height and the metal film thickness coated on grating surface on energy storage was analyzed in detail.It was found that the comparison between unoptimized and optimized surface grating structure on solar cells shows that the optimization of surface by grating significantly increases the energy storage capability and greatly improves the efficiency,especially of the photoelectric conversion efficiency and energy storage of the triangle grating.As the film thickness increases,energy storage effect increases,while as the film thickness is too thick,energy storage effect becomes lower and lower.
