DOI: 10.1126/sciadv.abc8844
Abstract: Low-temperature solution–grown large high-quality perovskite single crystals enable integrated circuits for imaging. The triple-cation mixed-halide perovskite (FAxMAyCs1-x-y)Pb(IzBr1-z)3 (FAMACs) is the best composition for thin-film solar cells. Unfortunately, there is no effective method to prepare large… read more here.
