摘　　要：以多孔氧化铝(AAO)为模板设计了一种新型的纳米光栅背反射结构。采用微波工作室(CST MWS)软件对该结构进行仿真,研究AAO模板的孔径大小、孔径深度和占空比对薄膜硅太阳能电池光吸收的影响。仿真结果表明,以AAO为模板制备的新型背反射结构能够有效地延长光的传播路径,增加长波长光子的吸收。当孔径大小为157.2 nm,孔深为78.6 nm,占空比为0.5时,效果最佳。这与理论的计算结果相一致。A new type of back reflectors were designed using anodic aluminum oxide（AAO） as the template. Simulate the back reflector by CST MICRO WAVE STUDIO（CST MWS）. The effects of aperture,hole depth and duty cycle of AAO on absorption of thin film silicon solar cell was researched. The results indicate that the new type of back reflectors can extend the light path and make the use of long-wave range of sunlight effectively. When aperture is 157. 2 nm,hole depth is 78. 6 nm and duty cycle is 0. 5,the result is best. This is consistent with the theoretical calculation results.
