A research team, headed by Yang Dong and Liu Shengzhong from the Dalian Institute of Chemical Physics at the Chinese Academy of Sciences, has achieved significant progress in the fabrication of perovskite solar cells. They have developed an innovative molecular glue interface anchoring technology, which effectively facilitates the coating and printing of high-efficiency, large-area perovskite components. This groundbreaking technology securely anchors tin oxide particles, thereby enhancing the stability of the solution, notably diminishing film surface roughness and pinhole defects. Furthermore, it fosters a tight bond between the electron transport layer and the perovskite light-absorbing layer, which reduces interface defect density and boosts charge extraction efficiency.
