This paper presents the second version of the efficiency tables of materials considered as emerging inorganic absorbers for photovoltaic solar cell technologies. The materials collected in these tables are selected based on their progress in recent years, and their demonstrated potential as future photovoltaic absorbers. The first part of the paper consists of the guidelines for the inclusion of the different technologies in this paper, the verification means used by the authors, and recommendation for measurement best practices. The second part details the highest world-class certified solar cell efficiencies, and the highest non-certified cases (some independently confirmed). The third part highlights the new entries including the record efficiencies, as well as new materials included in this version of the tables. The final part is dedicated to review a specific aspect of materials research that the authors consider of high relevance for the scientific community. In this version of the efficiency tables, we are including an overview of the latest progress in quasi one-dimensional absorbers, such as antimony chalcogenides, for photovoltaic applications.

本文介绍了被视为光伏太阳能电池技术新兴无机吸收剂的材料效率表的第二版。这些表格中收集的材料是根据它们近年来的进展以及它们作为未来光伏吸收器所展示的潜力来选择的。论文的第一部分包括在本文中包含不同技术的指南、作者使用的验证手段以及测量最佳实践的建议。第二部分详细介绍了最高的世界级认证太阳能电池效率，以及最高的非认证案例（一些独立确认）。第三部分重点介绍了包括记录效率在内的新条目，以及此版本表格中包含的新材料。最后一部分专门回顾了作者认为与科学界高度相关的材料研究的特定方面。在此版本的效率表中，我们概述了光伏应用中准一维吸收器（例如锑硫属元素化物）的最新进展。
