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
