A new and intelligent de-metalization step of broken silicon cells and silicon cell production waste in the recycling procedure of crystalline si modules

Recovering pure silicon from damaged or end-of-life PV modules can lead to environmental and economic benefits [1]. The chemical processing is a very important stage of the recycling process in order to achieve these benefits. In this regard, the authors found a new de-metalization step of broken silicon cells and silicon cells production waste, which resulted in a reduction of waste and they receive salable products.
