摘要
有机-无机杂化钙钛矿太阳能电池的光电转换效率已逾24%,效率的飞速提升加之可低成本溶液法制备的市场优势,使人们越来越期待钙钛矿太阳能电池的商业化.目前钙钛矿太阳能电池商业化所面临最大的障碍是材料乃至器件的长期不稳定性,这使其无法在使用寿命上与已商品化的硅基等太阳能电池匹敌.本文从化学不稳定性和相不稳定性两个层面剖析了有机-无机杂化钙钛矿材料本征不稳定性的问题,并从组分设计及制备工艺等角度给出了提高钙钛矿太阳能电池器件稳定性的相关建议.
The power conversion efficiency of organic-inorganic hybrid perovskite solar cell has exceeded 24%.The rapid increase in efficiency coupled with its cost-effective fabrication has attracted tremendous attention toward the commercialization of perovskite solar cells.The biggest challenge that hinders the commercialization of perovskite solar cells is the long-term instability of materials and the corresponding devices,which cannot compete with other commercialized solar cells,such as Si cells,in terms of lifetime.The intrinsic instability of perovskite material itself is the most critical challenge faced by researchers.In this study,we discuss the intrinsic instability of organic-inorganic hybrid perovskite materials from the aspects of both chemical instability and phase instability.Suggestions for improving the stability of perovskite solar cell are provided from the perspective of composition design and fabrication process.
