Lead Halide Hybrid Perovskites as Efficient Light Energy Harvesters
Professor Prashant V. Kamat, University of Notre Dame
Photoinduced charge separation in light harvesting materials is the primary step in light energy conversion devices. Semiconductor nanostructures with tunable photoresponse can capture the visible and near IR photons quite effectively. In recent years lead halide perovskite materials have emerged as the major contender for designing thin film photovoltaics. Photoexcitation of perovskite film leads to efficient charge separation and their recombination is found to be dependent on the excitation intensity. The chemistry of lead halide complex in precursor solutions can influence the formation of mixed halide perovskites. Factors that control the excited state dynamics in mixed halide perovskites offer new opportunities to tune the optical properties of hybrid perovskites. The photovoltaic performance and excited state behavior of CH3NH3PbI3 films will be discussed along with some recent results of quantum dot solar cells.
