摘要

以透明导电薄膜MoO3/Au/MoO3代替铟锡氧化物(ITO)作为有机太阳能电池(OSCs)的阳极,研究了一系列结构为MoO3/Au/MoO3的透明电极和MoO3(y nm)/Au(x nm)/MoO3(y nm)/CuPc(25 nm)/C60(40 nm)/BCP(8 nm)/Al(100 nm)的有机太阳能电池.研究表明,MoO3/Au/MoO3电极的光电特性可通过改变各层薄膜厚度加以调控,在MoO3薄膜厚度为40 nm、Au薄膜厚度为10 nm时性能最优,且以该薄膜为电极的有机太阳能电池器件的性能接近于电极为ITO的有机太阳能电池器件.%Transparent conductive film MoO3/Au/MoO3 was used as the anode of organic solar cells ( OSCs) instead of indium tin oxide ( ITO) . A series of MoO3/Au/MoO3 transparent electrodes and OSCs with the structure of MoO3(y nm)/Au(x nm)/MoO3(y nm)/CuPc(25 nm)/C60(40 nm)/BCP(8 nm)/Al(100 nm) were fabricated. The results show that the photoelectric characteristics of MoO3/Au/MoO3 electrode can be controlled by changing the film thickness of each layer, the opti-mum performance of OSC is achieved when the thickness of MoO3 film is 40 nm and the thickness of Au film is 10 nm. Besides, the performance of the OSC with MoO3/Au/MoO3 electrode is close to that of OSC with ITO electrode.
