钙钛矿太阳能电池材料的研究进展

摘要

Perovskite solar cells(PSCs) have been developed rapidly as one of the most remarkably growing photovoltaic technologies in the last five years.The power conversion efficiency(PCE) of the solar cells has been unprecedentedly increased over the relatively short period.It is of great significance to study the perovskite materials in this kind of solar cells for improving the efficiency.The most focused issues as well as the main progress in varied fabrication techniques and synthesis of new materials in recent years were reviewed in this paper.The characteristics and improvements of varied fabrication techniques are introduced in detail,the necessity and the problems facing for new materials synthesis were analyzed.Finally,a perspective view on reducing the toxicity of perovskite,preparing large-scale perovskite solar cells,and the cost reduction was given to provide the direction for the future research of high-efficiency and stable perovskite solar cells.%钙钛矿太阳能电池的研究在近5年内迅速发展,已经成为非常有活力的研究领域,在较短的时间内电池的效率得到了显著的提升.钙钛矿太阳能电池中钙钛矿材料的研究对于提高电池的效率有着重要的意义.本文综述了近年来在钙钛矿层制备方法、新材料的合成等方面存在的主要问题和研究进展.对各种制备方法的特点及改进优化进行了详细的介绍,并分析了新材料合成的必要性和所面临的问题.最后,指出了在降低钙钛矿毒性、大面积制备钙钛矿太阳能电池,以及降低成本等方面的研究前景,为今后高效、稳定的钙钛矿太阳能电池的研究提供方向.
