Abstract

Quantum dots have garnered significant interest in perovskite solar cells (PSCs) due to their stable chemical properties, high carrier mobility, and unique features such as multiple exciton generation and excellent optoelectronic characteristics resulting from quantum confinement effects. This review explores quantum dot properties and their applications in photoelectronic devices, including their synthesis and deposition processes. This sets the stage for discussing their diverse roles in the carrier transport, absorber, and interfacial layers of PSCs. We thoroughly examine advances in defect passivation, energy band alignment, perovskite crystallinity, device stability, and broader light absorption. In particular, novel approaches to enhance the photoelectric conversion efficiency (PCE) of quantum dot-enhanced perovskite solar cells are highlighted. Lastly, based on a comprehensive overview, we provide a forward-looking outlook on advanced quantum dot fabrication and its impact on enhancing the photovoltaic performance of solar cells. This review offers insights into fundamental mechanisms that endorse quantum dots for improved PSC performance, paving the way for further development of quantum dot-integrated PSCs.

先进量子点在钙钛矿太阳能电池中的应用：合成、表征、机理和性能增强。

量子点由于其稳定的化学性质、高载流子迁移率以及由量子约束效应产生的多激子产生和优异的光电特性等独特特性，在钙钛矿太阳能电池（PSCs）中引起了极大的兴趣。本文综述了量子点的性质及其在光电子器件中的应用，包括量子点的合成和沉积工艺。这为讨论它们在psc的载流子传输、吸收层和界面层中的不同作用奠定了基础。我们全面考察了缺陷钝化、能带对准、钙钛矿结晶度、器件稳定性和更广泛的光吸收方面的进展。特别强调了提高量子点增强钙钛矿太阳能电池光电转换效率（PCE）的新方法。最后，在综合综述的基础上，展望了先进量子点制造技术及其对提高太阳能电池光电性能的影响。本文综述了量子点提高PSC性能的基本机制，为量子点集成PSC的进一步发展铺平了道路。

期刊介绍： Materials Horizons is a leading journal in materials science that focuses on publishing exceptionally high-quality and innovative research. The journal prioritizes original research that introduces new concepts or ways of thinking, rather than solely reporting technological advancements. However, groundbreaking articles featuring record-breaking material performance may also be published. To be considered for publication, the work must be of significant interest to our community-spanning readership. Starting from 2021, all articles published in Materials Horizons will be indexed in MEDLINE©. The journal publishes various types of articles, including Communications, Reviews, Opinion pieces, Focus articles, and Comments. It serves as a core journal for researchers from academia, government, and industry across all areas of materials research. Materials Horizons is a Transformative Journal and compliant with Plan S. It has an impact factor of 13.3 and is indexed in MEDLINE.
