Perovskite solar cells that withstand photolysis and are stable under reverse bias

Nature Materials, Published online: 04 June 2024; doi:10.1038/s41563-024-01879-z

Photolysis and ion migration under electrical bias cause intrinsic instability in halide perovskite solar cells. By harnessing materials that both capture and confine iodide and polyiodide ions at the perovskite surface, the stability of devices under ultraviolet irradiation, thermal–light conditions or reverse bias can be greatly increased.Nature Materials, Published online: 04 June 2024; doi:10.1038/s41563-024-01879-zPhotolysis and ion migration under electrical bias cause intrinsic instability in halide perovskite solar cells.
