Using ultrafast infrared imaging techniques, a team of researchers from Penn State has revealed that the remarkable electronic properties of halide perovskite photovoltaic materials properties arise from large-scale motion of atoms in their crystalline lattice.

New insight into how a certain class of photovoltaic materials allows efficient conversion of sunlight into electricity could position these materials to replace traditional silicon solar cells. A study by researchers at Penn State reveals the unique properties of these inexpensive and quick-to-produce halide perovskites, information that will guide the development of next generation solar cells. The study appears September 27 in the journal Chem.
