Abstract

Two-dimensional (2D) perovskites with organic spacer ligands are promising materials with superior stability and diversity for various photovoltaic devices. While traditional perovskite precursor solutions using high boiling point solvents easily cause poor uniformity, we demonstrate a new method for rapid crystallization of 2D perovskite by adopting low boiling point solvents. Our results show that 2D perovskite films have a high quality and their processing is simplified and shortened. Photoconductors are made based on the 2D perovskite films and applied in visible light and X-ray detection effectively. These findings suggest the easily processed 2D perovskites promising for practical optoelectronic applications.
