Perovskite solar cell based on electron-rich surface passivation layer achieves 23.27% efficiency
Chinese in China have utilized two sulfone-based organic molecules known as diphenylsulfone (DPS) and 4,4′-dimethyldiphenylsulfone (DMPS) to passivate absorber defects in perovskite solar cells. The result is a device with a higher electron cloud density at the interface between the perovskite material and the passivation layer.
