We report air stable inverted organic photovoltaics (OPVs) incorporating graphene oxide (GO) and solution processed zinc oxide (ZnO) as hole transport and electron transport layers, respectively. Both the hole transport layer and the electron transport layer (HTL and ETL) are of advantage in high transparency and environmental stability. The use of GO and ZnO in poly(2,7-carbazole) derivative (PCDTBT):fullerene derivative (PC₇₀BM)-based inverted OPVs leads to an improved device stability and enhanced high open circuit voltage (V(oc)) of 0.81 V, a short-circuit current density (J(sc)) of 14.10 mA cm(-2), and a fill factor (FF) of 54.44 along with a power conversion efficiency of 6.20%.
我们报告了一种空气稳定的倒置有机光伏器件（OPV），其中包含氧化石墨烯（GO）和溶液处理的氧化锌（ZnO），分别作为空穴传输层和电子传输层。空穴传输层和电子传输层（HTL 和 ETL）都具有高透明度和环境稳定性的优势。在基于聚（2,7-咔唑）衍生物（PCDTBT）：富勒烯衍生物（PC₇₀BM）的倒置 OPV 中使用 GO 和 ZnO，可提高器件稳定性，并增强开路电压（V(oc)）至 0.81V、短路电流密度（J(sc)）至 14.10mAcm(-2)、填充因子（FF）至 54.44，以及功率转换效率为 6.20%。
