Swedish solar energy expert Midsummer and Chalmers University of Technology develops a unique process to recycle rare metals Stockholm, Sweden - Midsummer, a leading supplier of production lines for cost effective manufacturing of flexible thin film CIGS solar cells, has developed a unique process to recover leftover rare metals such as indium and gallium when manufacturing thin film CIGS solar cells. The unique process will extensively reduce thin film CIGS manufacturing material costs. In close cooperation with Professor Christian Ekberg and PhD-student Anna Gustafsson at the Swedish Chalmers University of Technology, Midsummer has developed a unique process to recycle the CIGS-material that
