Abstract

Photo-excitation intensity dependent electron and hole injections from CH3NH3PbI3 perovskite to nanocrystalline TiO2 and spiro-OMeTAD are presented with the electron injection yield decrease from 95% to 10% and the hole injection yield decrease from 99% to 50% by increasing the excitation intensity from 10 nJ cm(-2) to 50 μJ cm(-2).
