中文摘要：

近几年,基于有机-无机杂化的钙钛矿太阳能电池成为光伏材料领域的研究热点.同时作为新型太阳能电池,钙钛矿太阳能电池受到科学家的广泛关注.目前在实验室制备的电池能量转换效率已经超过21%.但是此类太阳能电池的稳定性存在很大问题,如果不能得到有效解决,必然会阻碍其产业化的进程.这几年关于如何提升钙钛矿太阳能电池稳定性方面的研究不断增多.文章归纳关于钙钛矿太阳能电池稳定性方面研究的最新进展.以CH3NH3PbI3为对象,对其物理、化学方面的稳定性问题以及整个电池器件内各层之间存在的界面稳定性问题进行阐述.最后回顾钙钛矿太阳能电池发展历程,对钙钛矿太阳能电池稳定性问题进行总结并从实际应用角度展望未来该领域的发展方向.

英文摘要：

In recent years,organic-inorganic hybrid perovskite solar cell（PSC） has become a highlight in the field of photovoltaic materials.As a new type of solar cell,the perovskite solar cell has been widely concerned by scientists all around the world.Recently,the power conversion efficiency（PCE） of PSC has been promoted to more than 21 % in laboratory.As is known to all,the poor stability of high efficiency devices is a stumbling block to the industrialization,and the research on how to improve the stability of perovskite solar cells has increased in recent years.This paper summarized the stability of the latest progress from perovskite as the absorbing light material was introduced into the solar cell research,focusing on two aspects about stability of material and device interface composition of perovskite solar cell.The interface stability of the whole cell was described with the stability of the physical and chemical properties of the CH3NH3PbI3 as the object.At last,the development course of perovskite solar cell was reviewed,and the stability of perovskite solar cell was summarized and the development direction of this field was also proposed from the point of view of practical application.
