Nowadays, obtaining a thin and large-area perovskite single-crystal (SC) is still challenging. Herein, we report a novel strategy to prepare a laminar MAPbBr SC with a controllable thickness of 16 μm and a size of 6 × 8 mm. Additionally, the SC solar cell achieves an intriguing efficiency of 7.11% with an impressive stability, maintaining 93% initial PCE after aging for 1000 h.
如今，获得大面积的超薄钙钛矿单晶（SC）仍然具有挑战性。在此，我们报道了一种制备层状MAPbBr单晶的新策略，其厚度可控，为16μm，尺寸为6×8mm。此外，该单晶太阳能电池实现了7.11%的可观效率，稳定性令人印象深刻，老化1000小时后仍保持初始光电转换效率的93%。
