Hybrid organic-inorganic perovskites are on the way to deeply transform the photovoltaic domain. Likewise, it recently appears that this class of materials have a lot of assets for other optoelectronic applications. One key aspect is to be able to synthesize large areas of monocrystalline thin films. Here, we report on the development of a new synthesis method of 2D hybrid organic-inorganic perovskite called "Anti-solvent Vapor-assisted Capping Crystalliza-tion". This method allows to grow monocrystalline thin films with high aspect ratio in less than 30 minutes.
