Metal halide hybrid perovskite solar cells (PSCs) have received considerable attention over the past decade owing to their potential for low-cost, solution-processable, earth-abundant, and high-performance superiority, increasing power conversion efficiencies of up to 25.7%. Solar energy conversion into electricity is highly efficient and sustainable, but direct utilization, storage, and poor energy diversity are difficult to achieve, resulting in a potential waste of resources. Considering its convenience and feasibility, converting solar energy into chemical fuels is regarded as a promising pathway for boosting energy diversity and expanding its utilization. In addition, the energy conversion-storage integrated system can efficiently sequentially capture, convert, and store energy in electrochemical energy storage devices. However, a comprehensive overview focusing on PSC-self-driven integrated devices with a discussion of their development and limitations remains lacking. Here, focus is on the development of representative configurations of emerging PSC-based photo-electrochemical devices including self-charging power packs, unassisted solar water splitting/CO reduction. The advanced progresses in this field, including configuration design, key parameters, working principles, integration strategies, electrode materials, and their performance evaluations are also summarized. Finally, scientific challenges and future perspectives for ongoing research in this field are presented.
在过去十年中，金属卤化物混合钙钛矿太阳能电池（PSCs）因其具有低成本、可溶液加工、储量丰富以及高性能优势的潜力而备受关注，其功率转换效率不断提高，最高可达25.7%。太阳能转化为电能高效且可持续，但直接利用、存储以及能源多样性差等问题难以解决，从而可能导致资源浪费。考虑到其便利性和可行性，将太阳能转化为化学燃料被视为增加能源多样性和扩大其利用的一条有前景的途径。此外，能量转换-存储集成系统可以在电化学储能装置中高效地依次捕获、转换和存储能量。然而，目前仍缺乏对PSC自驱动集成装置的全面综述，以及对其发展和局限性的讨论。在此，重点关注新兴的基于PSC的光电器件的代表性配置的发展，包括自充电电源组、无辅助太阳能水分解/CO还原。还总结了该领域的先进进展，包括配置设计、关键参数、工作原理、集成策略、电极材料及其性能评估。最后，提出了该领域正在进行的研究面临的科学挑战和未来展望。
