Outline of Research at the Start

The high-power conversion efficiency makes the perovskite solar cells increasingly competitive compared to traditional PV technologies. Toxic Pb-free, Sn-based perovskite solar cells (Sn-PSCs) are being researched as a green and potentially efficient next-generation PV system.
