Quantum dot-sensitized solar cells (QDSCs) have emerged as a promising candidate for next-generation solar cells due to the distinct optoelectronic features of quantum dot (QD) light-harvesting materials, such as high light, thermal, and moisture stability, facilely tunable absorption range, high absorption coefficient, multiple exciton generation possibility, and solution processability as well as their facile fabrication and low-cost availability. In recent years, we have witnessed a dramatic boost in the power conversion efficiency (PCE) of QDSCs from 5% to nearly 13%, which is comparable to other kinds of emerging solar cells. Both the exploration of new QD light-harvesting materials and interface engineering have contributed to this fantastically fast improvement. The outstanding development trend of QDSCs indicates their great potential as a promising candidate for next-generation photovoltaic cells. In this review article, we present a comprehensive overview of the development of QDSCs, including: (1) the fundamental principles, (2) a history of the brief evolution of QDSCs, (3) the key materials in QDSCs, (4) recombination control, and (5) stability issues. Finally, some directions that can further promote the development of QDSCs in the future are proposed to help readers grasp the challenges and opportunities for obtaining high-efficiency QDSCs.
量子点敏化太阳能电池（QDSCs）由于量子点（QD）光捕获材料的独特光电特性而成为下一代太阳能电池的有前途的候选者，例如高光、热和湿度稳定性、易于调节的吸收范围、高吸收系数、多激子产生的可能性、溶液加工性以及其易于制造和低成本可用性。近年来，我们见证了 QDSCs 的功率转换效率（PCE）从 5%到近 13%的急剧提高，这与其他新兴太阳能电池相当。新的 QD 光捕获材料的探索和界面工程都促成了这一惊人的快速改进。QDSCs 的卓越发展趋势表明它们作为下一代光伏电池的有前途的候选者具有巨大的潜力。在这篇综述文章中，我们全面介绍了 QDSCs 的发展，包括：（1）基本原理，（2）QDSCs 的简要演变历史，（3）QDSCs 中的关键材料，（4）复合控制，和（5）稳定性问题。最后，提出了一些可以进一步促进未来 QDSCs 发展的方向，以帮助读者把握获得高效 QDSCs 的挑战和机遇。
