In this podcast episode, MRS Bulletin’s Sophia Chen interviews Yen-Hung Lin of Hong Kong University of Science and Technology about his work to eliminate defects in perovskite solar cells. Lin’s group treated the perovskites with a category of molecules known as amino-silanes, which bind vacancies in the perovskites, preventing recombination of the electrons and holes. The amino-silane treatment retained the device’s performance at 95% power conversion efficiency for more than 1500 hours. This work was published in a recent issue of Science.
