Abstract

We have investigated the film morphology and photoluminescence properties of spin- coated CH₃NM₃Pbli₃xCl_x films on mesoporous and compact Ti02 substrates. We observe that the perovskite film deposited on the mesoporous substrate composed of 20 nm TiO₂ nanopaticles exhibits relatively uniform grain size, while the films deposited on the compact TiO₂ substrate and the mesoporous substrate with large TiO₂ nanoparticles (200 nm) show highly heterogeneous film morphology. The heterogeneity of film morphology has significant effect on the photoluminescence spectra and lifetime of the perovskite films. The result of time-resolved confocal microscopy unveils the relation between film structure and photoluminescence properties.
