Solution processed perovskite semiconductors have developed rapidly over the past decade to yield excellent performance in both solar cell and light emitting diode devices. Both of these device types are prepared using similar materials and architectures, raising the possibility of perovskite based light emitting solar cells. Recent reports have indicated that some low band gap perovskite solar cells are able to emit infrared light efficiently, however, intermediate band gap perovskite solar cells which emit visible light have not, to the best of our knowledge been deliberately designed or extensively characterized. In this work, we have investigated the use of different electron transport layers in order to minimize energetic barriers to electron injection and extraction in methylammonium lead bromide (MAPbBr₃) films. We demonstrate that through appropriate band structure engineering, MAPbBr₃ can be used to make such “peroptronic” light-emitting solar cells, which simultaneously exhibit efficient solar cell power conversion efficiencies over 1% and 0.43 lm W⁻¹ green light emission.

Peroptronic器件：基于钙钛矿的发光太阳能电池

在过去的十年中，经溶液处理的钙钛矿半导体发展迅速，在太阳能电池和发光二极管设备中均具有出色的性能。这两种类型的设备均使用相似的材料和体系结构制备，从而增加了钙钛矿基发光太阳能电池的可能性。最近的报道表明，一些低带隙钙钛矿太阳能电池能够有效地发射红外光，然而，据我们所知，没有专门设计或广泛表征发射可见光的中带隙钙钛矿太阳能电池。在这项工作中，我们研究了不同电子传输层的使用，以最大程度地减少对甲基铵溴化铅（MAPbBr ₃）电影。我们证明，通过适当的能带结构工程，MAPbBr ₃可用于制造这种“超电子”发光太阳能电池，该太阳能电池同时具有超过1％的有效太阳能电池功率转换效率和0.43 lm W ^-1的绿色发光。
