Gentle method allows for eco-friendly recycling of solar cells
By using a new method, precious metals can be efficiently recovered from thin-film solar cells. This is shown by new research from Chalmers University of Technology, Sweden. The method is also more environmentally friendly than previous methods of recycling and paves the way for more flexible and highly efficient solar cells. Today there are two mainstream types of solar cells. The most common is silicon-based and accounts for 90 percent of the market. The other type is called thin-film solar cells which in turn uses three main sub-technologies, one of which is known as CIGS (
