The research team, helmed by Professor Wang Zhiping of Wuhan University, has pioneered an atomic-scale interface bonding technique, tackling a pervasive industry challenge: simultaneously boosting both the efficiency and stability of perovskite solar cells. This innovative approach employs atomic layer deposition to incorporate a hafnium oxide interlayer at crucial interfaces within the cell, forming a robust bonding structure that significantly enhances interface stability. Leveraging this technology, the power conversion efficiency of p-i-n type perovskite solar cells soared to 27.1%, with a third-party certified efficiency of 26.6%. Notably, these cells retained over 90% of their initial efficiency after enduring more than 5,000 hours of operation under stringent conditions. Furthermore, the fabrication process of this technology is well-suited for large-scale production and elucidates the multifaceted synergistic stabilization mechanisms of the inorganic oxide interlayer.
