Recently, Zhu Xueliang, a young faculty member from the College of Sciences at China Jiliang University, made a breakthrough in the field of heterojunction design for perovskite solar cells. The relevant research findings were published in the prestigious journal Advanced Materials (IF=27.4, a top-tier journal in the Chinese Academy of Sciences). The paper is titled “A Surface Reconstructed Bilayer Heterojunction Enables Efficient and Stable Inverted Perovskite Solar Cells.” Zhu Xueliang is the first author, with the College of Sciences listed as the second affiliation.
This work presents an innovative surface reconstruction strategy and reveals the formation process and underlying physical mechanisms of a stable bilayer heterojunction (BLH) structure. This approach significantly reduces defect state density and open-circuit voltage loss, achieving groundbreaking advancements in the efficiency and long-term stability of perovskite solar cells, thereby promoting the commercialization process. This paper was funded by the National Key Research and Development Program (2022YFA1404900) and the National Natural Science Foundation (62074115)
