Abstract Despite rapid advancements in power conversion efficiency in the last decade, perovskite solar cells still perform below their thermodynamic efficiency limits. Non-radiative recombination, in particular, has limited the external radiative efficiency and open circuit voltage in the highest performing devices. We review the historical progress in enhancing perovskite external radiative efficiency and determine key strategies for reaching high optoelectronic quality. Specifically, we focus on non-radiative recombination within the perovskite layer and highlight novel approaches to reduce energy losses at interfaces and through parasitic absorption. By strategically targeting defects, it is likely that the next set of record-performing devices with ultra-low voltage losses will be achieved.

最大化混合钙钛矿太阳能电池的外部辐射效率

摘要 尽管在过去十年中功率转换效率取得了快速进步，但钙钛矿太阳能电池的性能仍然低于其热力学效率极限。特别是非辐射复合限制了最高性能器件的外部辐射效率和开路电压。我们回顾了在提高钙钛矿外部辐射效率方面的历史进展，并确定了实现高光电质量的关键策略。具体来说，我们专注于钙钛矿层内的非辐射复合，并强调减少界面能量损失和通过寄生吸收的新方法。通过战略性地针对缺陷，很可能会实现下一组具有超低电压损耗的性能记录设备。
