Towards stable solar cells, ferrocene as a perpetual recovering agent has been developed to fix all elemental defects in ABX3 perovskite by a chain-reaction cycle. The ferrocene cations can form a 1D perovskite structure which has suitable dissociation energy to convert back to light-harvesting 3D perovskite and reactivate its photovoltaic performance. Based on this recovering agent, perovskite solar cell can achieve >10 000 h lifetime.

二茂铁诱导的钙钛矿太阳能电池中所有元素缺陷的永久恢复

对于稳定的太阳能电池,已开发出二茂铁作为永久回收剂,通过链式反应循环修复 ABX 3钙钛矿中的所有元素缺陷。二茂铁阳离子可以形成一维钙钛矿结构,该结构具有合适的解离能,可以转换回捕光的3维钙钛矿并重新激活其光伏性能。基于这种回收剂,钙钛矿太阳能电池的寿命可达到 >10 000 小时。
