In this study we employed l-chloronaphthalene (CN) and 1,8-diiodooctane (DIO) as additives exhibiting preferential solubility for processing the crystalline conjugated polymer poly[(5,6-difluoro-2,1,3-benzothiadiazol-4,7-diyl)-alt-(3,3-di(2-℃tyldodecyl) 2.2 ;5,2;5,2-quaterthiophen-5,5-diyl)] (PffBT4T-20D):[6,6]-phenyl-C71-butyric acid methyl ester (PC7lBM) based Solar Cells.

小分子体异质结太阳能电池的性能与其薄膜的形貌,电荷产生,传输等是紧密相关的.我们制备了以DR3TSBDT:PC71BM 为有源层的小分子体异质结太阳能电池,来探究溶剂添加剂(DIO)对调控薄膜的形貌,加快电荷产生效率等方面的影响.不经过热退火,溶剂熏蒸等处理手段,器件的能量转换效率可以达到8.86％,这要高于文献目前报道的相同条件下的器件的能量转换效率(6.62％).通过采用溶剂添加剂的方法,其能
随着有机半导体材料的发展,有机光电探测器由于易制备、柔性等优点,近年来越来越受到关注.目前所报道的光电探测器多为二极管型光探测器,其显著的特点是外量子效率(EQE)小于100％,因此在实际使用中需要外置放大电路放大微弱的光生电流,这无疑会限制其应用范围且增加系统成本.
自1991年,Gr(a)tzel课题组首次使用多孔TiO2薄膜制备高效率染料敏化太阳能电池以来,多孔TiO2薄膜被广泛用于染料敏化太阳能电池中.重现性强的丝网印刷法适合于大规模生产高性能介孔TiO2薄膜,但由于一次性印刷难以得到一定厚度的TiO2薄膜,使用的TiO2薄膜一般通过多次印刷得到.

提高有机太阳能电池效率的关键之一是设计并合成高性能的给受体光伏材料.目前的高效率有机太阳能电池主要是以p型聚合物/小分子半导体为给体和以富勒烯衍生物为受体,光电转化效率已经超过11％.然而,富勒烯受体具有可见光区吸收弱、吸收光谱及能级调控难、高温下形貌不稳定等缺点,非富勒烯受体己在近年来表现出堪比富勒烯受体的优异光伏性能,受到了广泛关注.
有机太阳能电池一直以来因其价廉、质量小、制备工艺简洁等优点受到了广泛研究.1,2,3本文介绍了在有机太阳能电池空穴传输层夹一层金属薄膜以提高太阳能电池效率的实验.我们热蒸发了不同厚度的夹层金属薄膜来观测在有机太阳能电池中激发出的表面等离子体效应的不同来确定能使电池效率提升最多的夹层方式.

富勒烯受体材料在聚合物太阳能电池中占据统治地位,但其存在难以提纯,可见光区吸收弱和能级难以调控等缺点.相比之下,非富勒烯受体具有独特的优势,如合成方便、易于提纯和加工、吸收强而宽和能级易于调控等.近年来,非富勒烯有机太阳能电池发展迅速,设计合成新型非富勒烯受体材料、研究其结构和性能之间的关系十分有必要.
