Efficient perovskite solar cells via improved carrier management

Nature, Published online: 24 February 2021; doi:10.1038/s41586-021-03285-w

An improved device design for perovskite-based photovoltaic cells enables a certified power conversion efficiency of 25.2 per cent, translating to 80.5 per cent of the thermodynamic limit for its bandgap, which approaches those achieved by silicon solar cells.
