Reducing nonradiative recombination in perovskite solar cells with a porous insulator contact

A research team led by Prof. Xu Jixian from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) designed and fashioned a novel porous insulator contact (PIC) for perovskite solar cells. The PIC ameliorated the non-radiative charge recombination effect and the corresponding solar cell achieved an efficiency of up to 25.5%. The study was published in Science.
