Abstract

Organic photovoltaic devices based on a blend of poly(3-hexylthiophene) and a fullerene have been studied by inserting oriented zinc oxide nanopillars which were fabricated by a new method at low temperature (343 K). The dependence of the photovoltaic performance on the zinc oxide morphology was investigated, and it is concluded that the oriented zinc oxide nanopillar array plays an important role in collecting photogenerated electrons and acts as a conducting path to the electrode. Insertion of the oriented zinc oxide nanopillars in the photovoltaic cells produced enhanced performance with a power conversion efficiency of 1.22% under AM1.5 illumination.

摘要

通过插入采用新方法在低温（343K）下制备的取向氧化锌纳米柱，对基于聚（3 - 己基噻吩）和富勒烯混合物的有机光伏器件进行了研究。研究了光伏性能对氧化锌形态的依赖性，得出的结论是，取向氧化锌纳米柱阵列在收集光生电子方面起着重要作用，并作为通向电极的传导路径。在光伏电池中插入取向氧化锌纳米柱可提高性能，在AM1.5光照下功率转换效率为1.22%。
