Fast growth of monocrystalline thin films of 2D layered hybrid perovskite†
Hybrid organic–inorganic perovskites are on the way to deeply transforming the photovoltaic domain. Likewise, it recently appeared that this class of material has a lot of potential for other optoelectronic applications. One key aspect is to be able to synthesize monocrystalline thin films with large surface areas. Here, we report on the development of a new synthesis method for 2D hybrid organic–inorganic perovskite called “Anti-solvent Vapor-assisted Capping Crystallization”. This method allows us to grow monocrystalline thin films with a high aspect ratio in less than 30 minutes.
