As an abundant and non-toxic wide band gap semiconductor with a high electron mobility, ZnO in the form of nanowires (NWs) has emerged as an important electron transporting material in a vast number of nanostructured solar cells. ZnO NWs are grown by low-cost chemical deposition techniques and their integration into solar cells presents, in principle, significant advantages including efficient optical absorption through light trapping phenomena and enhanced charge carrier separation and collection. However, they also raise some significant issues related to the control of the interface properties and to the technological integration. The present review is intended to report a detailed analysis of the state-of-the-art of all types of nanostructured solar cells integrating ZnO NWs, including extremely thin absorber solar cells, quantum dot solar cells, dye-sensitized solar cells, organic and hybrid solar cells, as well as halide perovskite-based solar cells.
作为一种储量丰富、无毒且具有高电子迁移率的宽带隙半导体，纳米线（NWs）形式的ZnO已成为众多纳米结构太阳能电池中一种重要的电子传输材料。ZnO纳米线通过低成本化学沉积技术生长，将其集成到太阳能电池中原则上具有显著优势，包括通过光捕获现象实现高效光吸收以及增强电荷载流子的分离和收集。然而，它们也引发了一些与界面性质控制和技术集成相关的重大问题。本综述旨在详细分析集成ZnO纳米线的各类纳米结构太阳能电池的最新进展，包括超薄吸收体太阳能电池、量子点太阳能电池、染料敏化太阳能电池、有机和混合太阳能电池以及卤化物钙钛矿基太阳能电池。
