Research on low-temperature preparation and optoelectronic properties of key materials for planar heterojunction perovskite solar cells

Abstract

钙钛矿材料凭借优异的吸光性能、较长的载流子扩散长度、简便节能的合成加工工艺等亮点吸引了世界各国科学家们的广泛关注。钙钛矿太阳能电池的能量转化效率从最初的3.8%发展到22.1%仅仅历经数年的时间,呈现出光明的商业化前景。 基于对钙钛矿光伏器件研发现状的调研,本文对低温条件下制备高性能电子传输、钙钛矿吸光材料的成分优化途径以及钙钛矿器件磁滞效应的消除方法三个方面开展相关研究,为实现在低温条件下制备高性能钙钛矿太阳电池奠定基础。 首先,从钙钛矿材料成分和制作工艺的优化入手,本文重点探究由两步法制备(FAPbI3)x(MAPbCl3)1-x混合钙钛矿吸光层的最佳制备工艺,明确了PbI2前驱体的干...Organic-inorganic hybrid perovskite materials have drawn increasing attention for its outstanding performance in terms of light absorption coefficient, diffusion length of carriers and processing technology. The photoelectric conversion efficiency of perovskite solar cells (PSCs) has grown from the initial 3.8% to 22.1% for only a few years, showing a bright future of commercialization.
