Perovskite solar cell based on Mxene achieves record-breaking efficiency of 25.75%
A research team in Spain has built what it claims to be the world’s most efficient perovskite solar cell using MXenes or any other type of 2D-materials. The device relies on a Mxene interlayer that suppresses non-radiative recombination and improved charge extraction at the interface between the perovskite absorber and the electron transport layer.
