Mild oxalic acid process enables efficient indium recovery from heterojunction solar cells

A mild oxalic-acid-based hydrometallurgical process enables efficient indium recovery from indium tin oxide in solar cell waste while simultaneously releasing silver grids. The approach achieves high-purity indium oxide production through selective leaching, precipitation, and calcination under…
