Perovskite materials, most notably organo-lead iodide species, have recently demonstrated great potential in future high-performance photovoltaics. Our group has made contributions to addressing the complex scientific challenges in perovskite solar cells, leveraging a multidisciplinary background that spans materials science, information science, and energy science. Leveraging cross-disciplinary expertise, new hole transport materials and amidinium-based modifier molecules were designed and synthesized to achieve precise modulation of perovskite properties. Innovative characterization methodologies were employed to elucidate new mechanisms for the enhancement of device stability and regulate the surface electronic state of perovskite materials. Through the development of thick-film preparation techniques and electrical passivation strategies, high-efficiency perovskite/CIGS tandem solar cells were successfully realized. In this talk, I will present our recent progress in ! improving the stability, efficiency, and reproducibility of perovskite-based photovoltaics and discuss the potential for commercialization.
