Enhancing stability of hybrid perovskite solar cells by imidazolium incorporation

Hybrid perovskites based solar cells have demonstrated high conversion efficiency but poor long-term stability. This study reports on the results obtained after doping the CH3NH3PbI2.6Cl0.4 mixed halide perovskite with imidazolium (C3N2H5+, denoted IM) on the “A site” position of a perovskite, to im...
