CdTe panel is a leader among thin-film technologies for solar panels and, according to some studies, promises the lowest production cost compared with other PV technology currently available in the commercial market. Despite the importance and representativeness of this technology, most published studies focus on crystalline silicon (c-Si) modules. Therefore, this brief review provides a more up-to-date view of CdTe panels, containing waste generation, hazardousness, and several aspects involving recycling. This review also provides information on the supply and demand of metals, especially Tellurium. Some authors cite the supply of Tellurium as a barrier to increasing the production of this photovoltaic panel technology and that its recycling could be a good alternative to meet demand. In this sense, this review also presents some possibilities for recycling processes, including routes that already exist on an industrial scale.

CdTe 光伏技术：废物产生、回收和原材料需求概述

CdTe 面板是太阳能电池板薄膜技术的领先者，根据一些研究，与目前商业市场上的其他光伏技术相比，其生产成本最低。尽管这项技术具有重要性和代表性，但大多数已发表的研究都集中在晶体硅 (c-Si) 模块上。因此，这篇简短的评论提供了 CdTe 面板的最新观点，包括废物产生、危险性以及涉及回收的几个方面。该评论还提供了有关金属（尤其是碲）供需的信息。一些作者指出，碲的供应是增加这种光伏板技术产量的障碍，而其回收可能是满足需求的一个很好的替代方案。从这个意义上说，这篇评论还提出了回收过程的一些可能性，包括工业规模上已经存在的路线。
