Development of New Device and Process to Recover Valuable Materials from Spent Solar Module


Article Preview

As industry enters into high-tech society, the use of fossil energies is increasing. The demand of solar photovoltaic cell is increasing and according to this increase, the amount of waste photovoltaic cell will increase, too. However, compared to the increase of photovoltaic facility and technology, research about recycling method of waste photovoltaic cell is slow. Therefore, this study continued research to collect cooper and tin which are valuable metals from cooper ribbon electrode recovered from waste photovoltaic electrode. To effectively separate the coating layer when handling bulk of cooper ribbon electrode, heat treating furnace of hydrodynamic vibrating is developed and tin and cooper which are valuable metals are collected by using Hydro-metallurgical process used with nitric acid. The purity of cooper’s basic materials after heat treatment of hydrodynamic vibrating was 98.88wt.% and the purity of tin and cooper collected from the coating layer was measured as 98.07wt.% and 98.44wt.% each.
