A methodology to liberate critical metals in waste solar panel
The availability of critical metals is one of the driving factor to secure the transition of energy production to a renewable, low carbon one because of the material requirement in
For example, precious metals are vital to manufacture crystalline silicon solar panel and tellurium, germanium, indium and gallium are essential in thin film photovoltaic panels. However, the pressure on the supply of critical metals increases with the growth of photovoltaics.
Tongwei Solar (Hefei) Co., Ltd., a subsidiary of Tongwei Co., Ltd., has been awarded the EcoVadis Gold Medal for 2024, achieving a score of 78. While the Gold Medal is awarded to companies in the top 5% globally, Tongwei further distinguishes itself by ranking in the top 3% among over 130,000 companies worldwideacross various industries.
From the results presented above, milling alone does induce selective liberation for functional material in thin-film solar panels. Compared to another thin-film material, lithium-ion batteries, whose valuable metal concentrate in fine size fractions, functional materials are found to concentrate in coarse size fractions.
This study presents a systematic study aiming at the investigation of selective liberation of functional materials in CIGS solar panels during milling to examine the feasibility of grinding as a de-coating process to liberate and concentrate the critical metals.
