摘要

A notable development in photovoltaic (PV) technology, quantum dot solar cells (QDSCs), provides viable answers to the drawbacks of conventional silicon-based solar cells. Quantum dots (QDs) are tiny semiconductor particles with unique optical and electrical properties due to their quantum confinement, which allows for programmable bandgaps and broad-spectrum light absorption. This review explores the integration of QDs into various solar cell architectures, such as quantum dot-sensitized solar cells (QDSSCs), quantum dot heterojunction solar cells (QD-HJSCs), colloidal quantum dot solar cells (CQDSCs), and quantum dot-polymer hybrid solar cells (QD-PHSCs). Innovations in these areas have improved power conversion efficiency (PCE), stability, and scalability. Additionally, the commercial applications and market potential of QDSCs are discussed, focusing on building-integrated photovoltaics (BIPV) and portable solar technologies. Despite these advancements, challenges such as material stability, cost-effectiveness, and scalability remain, necessitating further research and development. The future of QDSCs will likely involve exploring non-toxic materials, improved encapsulation techniques, and developing hybrid devices that combine the strengths of different PV materials.
