| We investigate the excellent photovoltaic properties, such as suitable bandgap, high optical absorption and long carrier lifetime of organic-inorganic lead halide perovskites (mainly CH3NH3PbI3). To explain the large recombination time we propose the hypothesis that the formation of ferroelectric domains can separate the diffusion pathways of electrons and holes. We have found that a two-dimensional hole confinement in CH3NH3PbI3 is possible under room temperature conditions and is enhanced by the deformation of the inorganic PbI3 sublattice. Beside, to improve their photovoltaic performance, we explore the impact of point defects on their electronic structure through sub-bandgap absorption. | |
