Electric-Field Assisted Perovskite Crystallization for High-Performance Solar Cells

摘要

Organic/inorganic hybrid perovskite materials have good crystalline properties,suchas low cost, simple synthesis, and can beapplicable for a solutionprocess. Theseare ideal choice for planar heterojunction solar cells.However, controllable growth of perovskite crystal films plays a key role in the photoelectric conversion efficiency of photovoltaic devices.And it is very important to deposit and grow high quality perovskite crystal films, including film formationmethod, crystallization process, crystal structure, morphology and grain size control of the films.
