Extraction of Silver via Electrowinning for Solar Panel Recycling

Mentor:
Research Theme: Energy
FURI: Spring 2020

The purpose of the experiment is to develop a process for the extraction of silver from a hydrofluoric acid solution using electrowinning. The goal was to develop a method that uses a pure silver reference electrode and find the voltage that maximizes the mass recovery. The silver reference electrode was proven to be stable in the solution, but a high mass recovery rate has not yet been attained. In order to achieve a higher mass recovery, the peroxide in the solution needs to be reacted out fully before beginning the electrolysis.

Electrochemical Process for Metal Recovery from End of Life Photovoltaic Modules

Mentor:
Research Theme: Energy
FURI: Fall 2019

The goal of this project is to develop a process for recycling old photovoltaic modules to prevent waste modules from being scrapped. This recycling process will reduce the space taken in landfills by solar modules while reducing the need to mine new precious earth metals for production. The recycling process is profitable, and the recovered raw materials can be sold back to manufacturers. Moving forward the process needs to be optimized for a high-volume manufacturing process, which would allow all solar panels in circulation to be recycled.
