摘要

Five PEDOT:PSS:MoO_3 volume ratios (1:1, 1:2, 1:3, 1:4, 1:5) hybrid hole transport layer (HTL) were prepared by solution processed method. The cell structure was PET/ITO/PEDOT:PSS:MoO_3/P3HT:PCBM/Ca/Al. We investigated the effect of MoO_3 added into the traditional PEDOT:PSS hole transfer layer on the photovoltaic performance. From these results, we found that the short circuit current density (J_(sc)), fill factor (FF) and power conversion efficiency PCE of the cells with M0O3 are always higher than those of cell without MoO_3.The short-circuit current density, fill factor and power conversion efficiency of cells increased with increasing MoO_3 volume ratio from 1:1 to 1:3 and then decreased slightly when the volume ratio increased to 1:4 and 1:5. The cell with 1:3 volume ratio exhibited the highest J_(sc) of 9.41 mA/cm2, an increase of 22%, and the highest PCE of 2.74%, an increase of 39%, compared to the controlled cell using PEDOT:PSS layer. The addition of M0O3 increased the probability of exciton dissociation due to its high hole mobility, thereby enhancing the J_(sc) and FF.
