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. A group of researchers led by the Zhejiang University of Technology in China has proposed to use two sulfone-based organic molecules known as diphenylsulfone (DPS) and 4,4'-dimethyldiphenylsulfone (DMPS) to improve the performance of perovskite solar cells. They used the ...
