Scientists from the University of Leicester say they have found a new way of extracting silver from old solar panels. They say the method, which uses a type of salt water instead of acid, is more environmentally friendly.
The old method of getting silver from solar panels uses mineral acid to dissolve it, but the process is expensive and causes damage the environment. The new way uses chemicals from chicken feed (choline chloride) and de-icer (calcium chloride) to make a type of salty water called brine.
From an economic and productivity perspective in the recovery of silver from solar cells, the chemical leaching presents a viable technique. At present, the predominant method for leaching is the utilization of nitric acid, succeeded by precipitation with either NaCl or NaOH or by electrochemical refining.
There is a limited amount of silver left in the earth so people want to reuse the silver that is already being used. How does it work? The old method of getting silver from solar panels uses mineral acid to dissolve it, but the process is expensive and causes damage the environment.
Cyclic voltammetry (CV) and electrodeposition-redox replacement (EDRR) techniques were used to efficiently recover metals from the silicon solar cell waste. The determination of metal concentrations was carried out utilizing ICP-OES analysis, while SEM was employed to examine the physical structure of the deposited metal.
The team say the new process gets more than 90% of the aluminium and silver from the solar cells in just 10 minutes and that the quality of the silver is high so it can be reused easily.
