Large-scale aligned crystalline CH3NH3PbI3 perovskite array films†
Abstract
Owing to the lattice match, aligned CH3NH3PbI3 perovskite array films composed of CH3NH3PbI3 microribbons with the length at the sub-millimeter scale were fabricated on ST cut quartz which showed a fast photo-response. This method provides a simple and flexible approach to grow oriented crystalline CH3NH3PbI3 arrays at the millimeter scale.
