摘　　要：制备了结构为ITO/Rubrene/C70/BCP/Al的双层有机太阳能电池(OSCs),通过优化缓冲层BCP的厚度研究了BCP对OSCs性能的影响及其作用机理。实验发现,BCP厚为6nm时,器件的效率最高达到1.78%,同时获得了较大的开路电压0.901V。相对于没有缓冲层,器件的效率、短路电流、开路电压和填充因子分别提高了432.9%、74.8%、95.4%和55.5%。Bilayer cells with the structure of ITO/Rubrene/C70 / bathocuproine （BCP） / A1 were fabricated. The effects of BCP layer on the performance of the cells and its mechanism were studied by inserting BCP with different thicknesses between C70 and Al as buffer layer. The experiental results show that the power conversion efficiency of the cell is as high as 1. 78% with 6 nm BCP,and the open-circuit voltage is up to 0. 901 V simultaneously. Compared with the device without buffer layer,the power conversion efficiency, short-circuit current,open-circuit voltage and filling factor of Rubrene/C70 heterojunction solar cells with 6 rim BCP are enhanced by 432.9% ,74.8% ,95.4% and 55.5% ,respectively.
