Photovoltaic cells use semiconductors to convert sunlight into electrical current and are regarded as a key technology for a sustainable energy supply. Quantum dot-based solar cells have shown great potential as next generation, high performance, low-cost photovoltaics due to the outstanding optoelectronic properties of quantum dots and their multiple exciton generation (MEG) capability. This review focuses on QDs as light harvesters in solar cells, including different structures of QD-based solar cells, such as QD heterojunction solar cells, QD-Schottky solar cells, QD-sensitized solar cells and the recent development in organic-inorganic perovskite heterojunction solar cells. Mechanisms, procedures, advantages, disadvantages and the latest results obtained in the field are described. To summarize, a future perspective is offered.
光伏电池利用半导体将阳光转化为电流，被视为可持续能源供应的一项关键技术。基于量子点的太阳能电池由于量子点出色的光电特性及其多激子产生（MEG）能力，已展现出作为下一代高性能、低成本光伏器件的巨大潜力。本综述聚焦于量子点作为太阳能电池中的光捕获剂，包括基于量子点的太阳能电池的不同结构，如量子点异质结太阳能电池、量子点肖特基太阳能电池、量子点敏化太阳能电池以及有机-无机钙钛矿异质结太阳能电池的最新进展。描述了该领域的机制、过程、优点、缺点及最新成果。最后进行总结并给出未来展望。
