We are interested in elucidating the fundamental properties of novel perovskite solar cells. Our strategy is to investigate the atomic-scale mechanisms that underpin the structural, electronic, optical, and transport properties of organic-inorganic hybrid lead-halide perovskites such as CH3NH3PbI3.
