摘　　要：以MoO3为阳极修饰层,以Rubrene/C60为活性层,制备了正置和倒置异质结有机小分子太阳能电池。实验结果表明倒置器件的开路电压Voc、短路电流密度Jsc、填充因子FF和功率转换效率η比正置结构的器件分别提高了34%、20%、25%和102%。当插入BCP阴极缓冲层后,阻挡了热的Al原子对C60层的破坏,对倒置器件的性能没有明显的影响,但却显著改善了正置器件的性能,并分析了MoO3和BCP对倒置和正置器件的作用。The common and inverted heterojunction small-molecule organic solar cells with MoO3 as anode modification layer,Rubrene/C60 as active layer were prepared.The experimental results reveal that the inverted devices have better performance compared with the common ones,and the open circuit voltage（Voc）,short circuit current density（Jsc）,fill factor（FF） and power conversion efficiency（η） increased 34%,20%,25%,102%,respectively.Inserting BCP cathode buffer layer which preventing C60 from the damage by hot Al atoms depostion does not affect the performances of the inverted devices,but markedly improves those of common ones.The influence of MoO3 and BCP on the device performances is analyzed.
