| 摘 要： | 通过不断降低钙钛矿的带隙,拓宽光活性层的光吸收范围是提高钙钛矿太阳能电池光电转换效率的一个有效途径.本文通过在三碘亚铅酸甲脒(HC(NH2)2PbI3简称FAPbI3)前驱液中混入一定比例的碘化甲铵(CH3NH3I简称MAI)并将其退火温度从150 ℃降低到100 ℃,不仅能有效改善钙钛矿薄膜的表面形貌和结晶度,还能得到比三碘亚铅酸甲铵(CH3NH3PbI3简称MAPbI3)更窄带隙的薄膜,由此得到效率达14.8;钙钛矿太阳能电池器件.

| Abstract: | It is an effective way to improve the photoelectric conversion efficiency of perovskite solar cells by cutting down the band gap of perovskite and broadening the range of optical absorption.In this paper, formamidine triiodoplumbite (HC(NH2)2PbI3 or FAPbI3) precursor solution mixed with a certain proportion of methyl ammonium iodide (CH3NH3I or MAI) and the annealing temperature of perovskite thin film is reduced from 150 ℃ to 100 ℃.The surface morphology and crystallinity of the films can not only effectively improve, but also get more than methyl ammonium triiodoplumbite (CH3NH3PbI3 or MAPbI3) narrow gap the film.The efficiency of perovskite photovoltaic cells is 14.8%. |
