尽管在过去的十年中，钙钛矿型太阳能电池在电力转换效率方面取得了快速的进步，但它的性能仍然低于其热力学效率极限。尤其是，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。我们回顾了提高钙钛矿外辐射效率的历史进展，并确定了达到高光电子质量的关键策略。具体地说，我们着重于钙钛矿层内的非辐射复合，并强调了通过寄生吸收来减少界面能量损失的新方法。通过战略性地瞄准缺陷，很可能会实现下一套具有超低电压损失的创纪录的性能设备。
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.
