Abstract

In article number 2000453, Weili Yu, Chunlei Guo and co-workers demonstrate that by combining the space-limiting technique and the anti-temperature crystallization method, millimeter sized MAPbI3 perovskite monocrystals with thickness from tens of nanometers to micrometers can be fabricated. Solar cells based on the 300 nm thick perovskite monocrystal are prepared, which show 3% enhancement in power conversion efficiency (PCE) compared to their polycrystalline counterparts. This work provides a scalable way to synthesize high quality perovskite crystals with less grains and grain boundaries, is believed a key step to develop perovskite single crystal solar cells with high performance.
