摘要
钙钛矿太阳电池(PSC)具有高光电转换效率(PCE)、低成本、易采用溶液法制备等特点,在发展轻薄、便携的柔性太阳电池方面有独特优势,可用于可穿戴设备、光伏建筑等领域。由于在柔性衬底上沉积均匀和高质量的钙钛矿薄膜颇具挑战性,目前,单结柔性钙钛矿太阳电池的PCE虽已经达到24.08%,但仍落后于刚性钙钛矿太阳电池(认证PCE为26.1%);此外,柔性钙钛矿薄膜在制备和弯曲循环过程中会不可避免地产生晶界裂纹,这也为柔性钙钛矿太阳电池的稳定性和可靠性带来巨大挑战。系统地评述了提升柔性钙钛矿太阳电池PCE和稳定性的研究进展,从柔性衬底、晶粒调控、晶界增强、界面钝化及结构优化等不同角度进行了归纳总结,并对柔性钙钛矿太阳电池未来发展存在的问题和挑战进行了展望。
Characterized by high photoelectric conversion efficiency(PCE),low cost and easy be prepared by solution process,perovskite solar cells(PSCs)have a unique advantage in the development of thin,lightweight and portable flexible solar cells,which can be used in wearable devices,photovoltaic buildings and other fields.At present,due to the challenge of depositing uniform and high-quality perovskite films on flexible substrates,the PCE of single juction flexible perovskite solar cells has reached 24.08%,but still lags behind rigid perovskite solar cells(certified PCE is 26.1%).Moreover,the inevitable generation of grain boundary cracks in flexible perovskite films during preparation and bending cycles poses a great challenge to the stability and reliability of flexible perovskite solar cells.The research progress in improving the PCE and stability of flexible perovskite solar cells is systematically reviewed and summarized from different perspectives,such as flexible substrate,grain modulation,grain boundary enhancement,interfacial passivation and structural optimization.Finally,the problems and challenges for the future development of flexible perovskite solar cells are prospected.
