Swedish researchers have developed a more environmentally sound means of recovering high-purity silver and indium from flexible thin-film solar cells, which are an up-and-coming clean energy alternative with a growing array of applications.

Swedish researchers at the Chalmers University of Technology have developed a recovery method for recycling 100% of the silver and about 85% of the indium contained in thin-film solar cells in an environmentally friendly, room temperature process.

"The problem is that the demand for indium and silver is high, and increased production is accompanied by a growing amount of production waste, which...
