摘要： In this study, four kinds of structures—[6,6]-phenyl-C61-butyric acid methyl ester (PCBM), PCBM/fullerene (C60), C60/bathocuproine (BCP), and PCBM/C60/BCP—were used as electron transport layers, and the structure, and optical and electronic behaviors of MAPbBr3 perovskite layers after annealing treatments were observed. The experimental results indicate that PCBM/C60 bi-layer structure is acceptable for MAPbBr3 planar perovskite solar cells due to electron step transporting. Low-temperature annealing is suitable for smooth and large grain MAPbBr3 films. The semi-transparent yellow C60/PCBM/MAPbBr3/PEDOT:PSS/ITO glass-structure solar cells exhibit the best performance with a power conversion efficiency of 4.19%. The solar cells are revealed to be suitable for application in building integrated photovoltaic (BIPV) systems. 出版者： Basel: MDPI AG 出版日期： 2016-12-01 出處： Coatings, 2016-12, Vol.6 (4), p.53--53 資源來源： Publicly available content database 版權： Copyright MDPI AG 2016 識別號： ISSN: 2079-6412 識別號： EISSN: 2079-6412 識別號： DOI: 10.3390/coatings6040053
