近日，香港科技大学工学院的研究团队在钙钛矿太阳能电池领域取得重大突破，通过创新的手性构型界面微结构技术，显著提高了电池的可靠性和光电转换效率。相关研究成果已在国际顶级科学期刊《科学》上发表。
钙钛矿太阳能电池作为一种新型薄膜太阳能电池，以其低成本、简单制造工艺而受到广泛关注。与传统硅太阳能电池相比，钙钛矿电池无需昂贵的高温、高真空工艺，可采用溶液印刷工艺制成，这使得其具有广阔的商业化前景。然而，户外环境下的长期耐久性问题一直是钙钛矿电池商业化的一大障碍。
研究团队受天然手性材料的机械强度启发，在钙钛矿太阳能电池中首创性地构建了手性结构界面。这种界面不仅坚固且具有弹性，还能够有效提升电池的耐久性。经过国际电工委员会（IEC）61215标准的严格测试，封装的太阳能电池在-40°C至85°C之间的极端温度循环200次后，仍能保持92%的初始转换效率，这一成果标志着钙钛矿太阳能电池的耐久性得到了显著提升，为其实际应用和商业化进程奠定了坚实基础。
此次研究成果的发表，不仅展示了香港科技大学在新能源领域的科研实力，也为全球太阳能电池技术的进步提供了新的思路和可能性。随着研究的深入和技术的成熟，未来钙钛矿太阳能电池有望在更广泛的领域得到应用，为解决能源危机和推动可持续发展做出贡献。

News Content:
Recently, a research team from the School of Engineering at Hong Kong Polytechnic University made a significant breakthrough in the field of perovskite solar cells. They achieved this by innovating a chiral configuration interface microstructure technique, which significantly enhanced the reliability and photoelectric conversion efficiency of the cells. The related research findings have been published in the prestigious international scientific journal Science.
Perovskite solar cells, as a new type of thin-film solar cell, have attracted widespread attention due to their low cost and simple manufacturing process. Compared with traditional silicon solar cells, perovskite cells do not require expensive high-temperature and high-vacuum processes; they can be fabricated using solution printing technology, which offers a promising commercial future. However, the long-term durability issue in outdoor environments has long been a major obstacle to the commercialization of perovskite solar cells.
Inspired by the mechanical strength of natural chiral materials, the research team created a chiral structure interface in perovskite solar cells for the first time. This interface is not only robust and elastic but also effectively enhances the durability of the cells. After rigorous testing according to the International Electrotechnical Commission (IEC) 61215 standard, the encapsulated solar cells maintained 92% of their initial conversion efficiency after 200 temperature cycles between -40°C and 85°C. This achievement signifies a significant improvement in the durability of perovskite solar cells, providing a solid foundation for their practical applications and commercialization.
The publication of this research outcome not only demonstrates Hong Kong Polytechnic University’s research strength in the field of new energy but also offers new ideas and possibilities for the advancement of global solar cell technology. With further research and technological maturity, perovskite solar cells are expected to be applied in a wider range of fields, contributing to solving the energy crisis and promoting sustainable development.
