In just one week, Professor Zhou Huanping from the School of Materials Science and Engineering at @PKU1898 Peking University published two papers in the top international academic journal Science.
On January 9, Professor Zhou Huanping and Professor Zhang Yanfeng (co-corresponding authors) published a research paper titled “Wafer-scale monolayer MoS2 film integration for stable, efficient perovskite solar cells” in Science. On January 16, Professor Zhou Huanping, as the sole corresponding author, published another research paper titled “Nonalloyed ?-phase formamidinium lead triiodide solar cells through iodine intercalation” in Science. These are two consecutive publications within a week in Science on the progress of perovskite solar cell research by Professor Zhou Huanping’s team.
This is an impressive achievement by Professor Zhou Huanping and his team, showcasing their significant contributions to the field of perovskite solar cell research. Publishing two high-impact papers in Science within a week highlights the team’s cutting-edge work and their ability to address critical challenges in renewable energy technology.
Key Highlights of the Research:
- Wafer-scale Monolayer MoS2 Film Integration for Stable, Efficient Perovskite Solar Cells (January 9):
- This study focuses on integrating monolayer molybdenum disulfide (MoS2) into perovskite solar cells to enhance their stability and efficiency.
- MoS2, a two-dimensional material, acts as a protective layer, improving the durability of perovskite solar cells while maintaining high power conversion efficiency.
- The wafer-scale integration technique demonstrated in this work is a significant step toward the commercial viability of perovskite solar cells.
- Nonalloyed ?-phase Formamidinium Lead Triiodide Solar Cells Through Iodine Intercalation (January 16):
- This paper addresses the challenge of stabilizing the ?-phase of formamidinium lead triiodide (FAPbI3), a highly efficient but unstable perovskite material.
- The team introduced a novel approach using iodine intercalation to stabilize the ?-phase without alloying, which preserves the material’s excellent optoelectronic properties.
- This breakthrough could lead to more efficient and durable perovskite solar cells, further advancing their potential for large-scale deployment.
