摘　　要：随着有机太阳能电池的发展,界面层在提高器件性能方面起着重要的作用,所以对界面层的研究越来越多。主要研究了溶液法制备的NiO薄膜作为阳极界面层在有机太阳能电池中的应用。研究发现,利用乙醇作为溶剂制备的NiO薄膜的表面形貌和结晶性受退火温度影响,通过优化300℃是一个比较合适的退火温度,在此温度下退火得到的NiO薄膜表现出比较好的连续性和结晶性。以此薄膜为阳极界面层制备的器件相比以PEDOT∶PSS为阳极界面层器件表现出了更好的性能。以NiO为界面层的P3HT∶PC61BM器件效率达到了4.27%,FF达到了70%。The interface layer plays an important role in the improvement of device performance and has paid much attention as the development of organic solar cells.NiO films were prepared with solution-processed method and used as the anode interface layer of organic solar cells.The surface morphology and crystallinity of NiO films showed the temperature dependence.And the films displayed relatively good continuity and crystallinity at the annealing temperature of 300℃.The device based on NiO films as anode exhibited better performance than that of PPDEOT∶PSS as anode.P3HT∶PC61BM solar cells based on NiO films showed high energy conversion efficiency of 4.27% with high FFof 70%.
