摘　　要：本文采用CuPc作为电子给体,C60作为电子受体制备了ITO/CuPc/C60/Al异质结太阳能电池。实验表明器件中活性层(CuPc/C60)对太阳能电池的光电性能有很大的影响。主要原因是有机物的激子扩散长度大约是十几纳米左右,产生的激子大多数在未到达异质结之前就已经复合。本文讨论了活性层(CuPc/C60)的厚度比,并获得其最优比例。In this work, copper phthalocyanine （CuPc） and buckminsterfullerene （C60） were used as do- nor and acceptor, resprcively, in organic photovoltaic （PV） solar cells with a structure of ITO/CuPc/C60/ Al. It was found that the performance of PV was sensitive to the thickness of active layer （CuPc and C60 ）. Because of the limited exciton diffusion length L, i.e. the characteristic distance over which excitons migrate before recombining, the thickness of a photoaetive layer in organic solar cells is often limited to the values typically of the order of L. In present work, the optimal thicknesses ratio of CuPc to C60 as active layers were discussed in deail.
