Hybrid perovskite solar cells
Research
A hybrid (organic-inorganic) halide perovskites solar cell is formed of a perovskite structured material such as methylammonium (MA) lead halides and represent a new photovoltaic technology that potentially offers efficient solar cells at very low cost and with extremely short energy pay-back times. Some examples from our research are phase transition analysis, lead replacement, stabilization of charge states, crystallization behavior, theoretical and experimental Stark and Raman spectroscopy.

(c) Lead halogen perovskite illustrating the cuboctahedral coordination around the organic ion. (d) CH3NH3PbI3 with the methylammonium ions explicitly. e) (below) Schematic illustration of the photoinduced Stark effect in lead halogen perovskites. Figures are from our work on lead replacement (J. Phys. Chem. C 2015, 119, 25673) and investigation of the photoinduced Stark effect (ACS Nano, 2017, 11, 2823).
