DOI: 10.1021/acs.jpcc.8b06160
Abstract: Methylammonium lead iodide (CH3NH3PbI3) has emerged as a superior light-absorbing material for perovskite solar cells, mainly because of its excellent optical and electronic properties. However, insufficient long-term stability of CH3NH3PbI3 has severely hindered its practical… read more here.
