摘要
本文主要研究了ZnO薄层的插入对P3HT∶PCBM为活性层的有机太阳能电池性能的影响,由于ZnO的功函数接近PCBM有利于电子的传输和ZnO低的HOMO起到阻挡空穴的作用,从而平衡电子和空穴的传输;在活性层和A l电极之间插入3 nm的ZnO薄层作为空穴阻挡层和电子选择层,使得电池转化效率由2.65%提高到3.45%。研究表明,由于ZnO薄层有利于改善活性层内部光场强度分布,从而使活性层的吸收进一步增强,进而达到了提高效率的目的。
The effects of insertion of ZnO thin layer on organic solar battery performance with P3HT∶PCBM for active layerswere were studied,because of the influence of ZnO reactive functions PCBM conducive to close to the transmission and electronic ZnO low HOMO plays the role of block cavity,thus balance electronic and cavities transmission;In the active layer and Al electrodes between insert 3 nm ZnO thin layer as the cavitation linings and electronic choice layer,making battery efficiency of conversion increased from 2.65% to 3.45%.Bcause ZnO thin layer could improve the active layer internal light field intensity distribution,the active layer absorption was further strengthen,thus the purpose of improving efficiency was achieved.
