摘要

鉴于太阳能作为清洁能源的重要地位，太阳能电池在发电总量中所占比例呈现显著增长趋势。这一增长同时带来了废弃太阳能电池数量的大幅增加，其中废晶硅太阳能电池板尤为突出，其处理方式已成为行业关注的焦点。为此，研究人员已运用热分解法和有机溶剂溶解法，成功将太阳能电池板中的EVA胶进行分解，并有效分离出硅晶片。通过湿法冶金和火法冶金技术，对硅晶片中的银进行了回收，这一成果为废弃太阳能电池的高效处理和资源回收提供了重要途径。对从废晶硅太阳能电池板中回收银的过程进行了全面回顾，分析了不同回收技术的利与弊，为银的有效回收提供科学依据。

Abstract：

Given the important role of solar energy as a clean energy source, the proportion of solar cells in total electricity generation is showing a significant upward trend. However, It has also led to a significant increase in the number of discarded solar cells, with waste crystalline silicon solar panels being particularly prominent, and their disposal methods have become a focus of industry attention. Researchers have successfully decomposed EVA adhesive in solar panels using thermal decomposition and organic solvent dissolution methods, and effectively separated silicon chips. Silver was recovered from silicon chips through wet metallurgy and pyrometallurgy techniques, which provides an important pathway for efficient processing and resource recovery of discarded solar cells. It provided a comprehensive review of the process of recovering silver from waste crystalline silicon solar panels. The advantages and disadvantages of different recovery technologies were analyzed, and aimed to provide scientific basis for the effective recovery of silver.

Key words： waste crystalline silicon solar cells EVA adhesive recycled silver hydrometallurgy pyrometallurgy
