Research Highlights: Manipulating the Mixed-Perovskite Crystallization Pathway Unveiled by In Situ GIWAXS
Mixed perovskites have achieved substantial successes in boosting solar cell efficiency, but the complicated perovskite crystal formation pathway remains mysterious. Here, we report for the first time the detailed crystallization process of mixed perovskites (FA0.83MA0.17Pb(I0.83Br0.17)3) during spin-coating by in situ GIWAXS measurements, and three phase formation stages have been identified: I.… Read More
