The latest progress and future perspectives of thin film photovoltaic kesterite technology are reviewed herein. Kesterite is currently the most promising emerging fully inorganic thin film photovoltaic technology based on critical raw-material-free and sustainable solutions. The positioning of kesterites in the frame of the emerging inorganic solar cells is first addressed, and the recent history of this family of materials briefly described. A review of the fast progress achieved earlier this decade is presented, toward the relative slowdown in the recent years partly explained by the large open-circuit voltage (V ) deficit recurrently observed even in the best solar cell devices in the literature. Then, through a comparison with the close cousin Cu(In,Ga)Se technology, doping and alloying strategies are proposed as critical for enhancing the conversion efficiency of kesterite. In the second section herein, intrinsic and extrinsic doping, as well as alloying strategies are reviewed, presenting the most relevant and recent results, and proposing possible pathways for future implementation. In the last section, a review on technological applications of kesterite is presented, going beyond conventional photovoltaic devices, and demonstrating their suitability as potential candidates in advanced tandem concepts, photocatalysis, thermoelectric, gas sensing, etc.
本文综述了薄膜光伏硫系铜矿技术的最新进展和未来展望。硫系铜矿目前是最具前景的新兴全无机薄膜光伏技术，基于无关键原材料且可持续的解决方案。首先阐述了硫系铜矿在新兴无机太阳能电池框架中的定位，并简要介绍了该材料家族的发展历程。回顾了本世纪头十年取得的快速进展，近年来进展相对放缓，部分原因是即使在文献中最好的太阳能电池器件中也经常观察到较大的开路电压（V）损失。然后，通过与近亲铜铟镓硒技术进行比较，提出掺杂和合金化策略对提高硫系铜矿的转换效率至关重要。在本文的第二部分，对本征和非本征掺杂以及合金化策略进行了综述，展示了最相关和最新的结果，并提出了未来实施的可能途径。在最后一部分，对硫系铜矿的技术应用进行了综述，超越了传统光伏器件，并证明了它们作为先进串联概念、光催化、热电、气体传感等潜在候选材料的适用性。
