摘要：

Effect of WO3-V2O5 mixed oxides as anodic modification through simple solution processing is investigated to improve the efficiency and stability of inverted polymer photovoltaic devices. The power conversion efficiency is improved from 3.1% to 4.16% with good air stability (> 90% of efficiency retained over 1000 h). Our investigations show that the mixed oxides can suppress the leakage current, enhance the light absorption, and provide a temporally durable device. The mixed oxides function better than the pristine oxides (V2O5 or WO3) as the anode modification in terms of photovoltaic performance.
