Organometal trihalide perovskite-based solid-state hybrid solar cells have attracted unexpected increasing interest because of the high efficiency (the record power conversion efficiency has been reported to be over 17％) and low cost for preparation.1) The high efficiency was thought to mainly originate from the strong optical absorption over a broader range (up to 800 nm for Pb) and longer lifetimes of photoexcited charge carriers(in the order of 10 ns-100 ns) of the organometal trihalide perovskite absorbers.

PbS量子点以摩尔消光系数高、合成加工手段多样、带隙与太阳光谱匹配等优点,成为一种理想的太阳能电池材料.自2005年至今,PbS量子点太阳能电池效率快速上升,达到8.55％(NewPort Certified).然而平面异质结结构对太阳光的利用率有限,IPCE测试表明电池在PbS量子点第一激子吸收峰附近的外量子效率只有不到50％,而太阳光近红外部分能量在整个光谱中占有相当大的比重,因此提高电池对太
近年来,胶体量子点在量子点敏化太阳能电池(QDSCs)中展现出了潜在的应用前景,并获得了6-8％的转换效率.其中,CdSeTe合金量子点因其较宽的吸光范围以及高的化学稳定性得到人们的关注,获得了7.54％的效率.尽管如此,QDSCs的效率仍然远低于传统的染料敏化太阳能电池(DSSCs),而严重的载流子复合是限制其转换效率的重要因素之一.
纳米四角体在构建杂化体异质结薄膜太阳能电池中的电子受体与传输体时具有独特的优势[1].我们在本工作中研制出一种新型的具有核壳结构的硒化镉/硫化铅(CdSe/PbS NTs)纳米四角体.这种复合材料由4nm左右的PbS量子点均匀修饰在CdSe纳米四角体表面,形成了具有Ⅱ型能级结构搭配的异质结界面.与纯CdSe纳米四角体相比,这种核壳结构CdSe/PbS NTs在与P3HT半导体高分子复合时能更有效地
铜锌锡硫(Cu2ZnSnS4,CZTS)基薄膜太阳电池以其优异的性能和具有矿源丰富、环境友好的特性,成为当前薄膜太阳电池研究领域的新方向.发展低成本的制备方法、提高光吸收层质量、优化电池结构与界面等是该类电池目前面临的一些主要问题.针对这些问题,本文采用低成本的溶胶-凝胶涂覆法制备铜锌锡硫基薄膜太阳电池,通过原位掺杂、刻蚀和低压硫化等工艺改善薄膜的结晶质量和钝化缺陷,通过引入中间层来优化CZTS/
