The main solutions to the current stability problems of perovskite solar cells include the development of more stable 2D/3D perovskite structures,the development of new additives to control the growth of grains using the interfacial medication methods,and the selection of suitable hole and electron transport materials with superior properties KEY WORDS perovskite solar cell;stability:structure;influencing factors;regulation 收稿日期：2019-06-24 基金项目：中央高校基础研究基金资助项目(230201606500078)：国家自然科学基金资助项目(U1702252.01302274,51674026)钙钛矿太阳能电池稳定性研究进展 朱    彧，杜    晨，王    硕，马瑞新，王成彦苣 北京科技大学冶金与生态工程学院，北京 100083 苣通信作者，E-mail：chywang@yeah.net 摘    要    从钙钛矿晶格结构和器件结构入手，介绍了钙钛矿电池的发展历程，总结了 A 位，B 位及 X 位的组分调控方法、一 步法、两步法及其他成膜方法，形貌控制方法，最后，详细讨论了钙钛矿太阳能电池稳定性的影响因素，光热湿等因素是引起 钙钛矿晶体分解，导致电池性能下降的主要原因. 最后，稳定性问题已经成为阻碍钙钛矿电池产业化的最大的障碍，介绍了 钙钛矿太阳能电池当前稳定性问题的主要解决方案：开发更稳定的钙钛矿结构，开发用于控制晶粒生长的新添加剂，以及选 择具有优异性能的空穴传输层和电子传输层. 关键词    钙钛矿太阳能电池；稳定性；结构；影响因素；调控 分类号    O472 Research progress on the stability of perovskite solar cells ZHU Yu，DU Chen，WANG Shuo，MA Rui-xin，WANG Cheng-yan苣 School of Metallurgical and Ecological Engineering, University of Science and Technology Beijing, Beijing 100083, China 苣 Corresponding author, E-mail: chywang@yeah.net ABSTRACT    In recent years, with the rapid development of new energy and industrial technologies, the solar cell industry has begun to receive considerable attention. Perovskite solar cells are regarded as the third-generation solar cells. As of April 2019, on the basis of the international certification, the maximum power conversion efficiency of perovskite solar cells is 24.2%, which is similar to the highest power  conversion  efficiency  of  silicon  solar  cells.  Perovskite  solar  cells  exhibit  high  power  conversion  efficiency,  low  cost,  simple preparation, and diversity of structure, which makes them the leaders in next-generation thin-film photovoltaic devices. In this paper the development history of perovskite solar cells was reported; the perovskite crystal structure and device structure were discussed in detail; and a tolerance factor for obtaining a more stable perovskite structure was introduced. We then summarized the A-site, B-site, and X-site composition engineering, the one-step, two-step and other fabrication methods and morphology control methods of perovskite thin films that  could  stabilize  the  perovskite  crystal  structure,  reduce  the  pollution  and  harm  of  lead  in  perovskite  films,  control  the  growth  of perovskite film, and regulate the band gaps. In addition, the influencing factors on the stability of perovskite solar cells was also discuss; light stability, thermal stability, and humidity stability that are the main causes of the decomposition of perovskite crystals, resulting in a serious decrease in device performance owing to the phase transition and degradation. The biggest obstacle for the industrialization of perovskite solar cells is the stability. Finally a series of methods that can improve the stability of perovskite solar cells were analyzed.
