The aim of this project is to develop buffers for chalcopyrite solar cells that make them suitable for production. Therefore a threefold effort will be followed:- make Cads as save as possible by relevant recycling procedures- develop Cd-free buffer materials and their recycling procedures- develop dry in-line compatible deposition methods Improved material yield, relaxed safety conditions and simplicities process management will reduce production costs for these highly efficient and lox-toxic modules. Material and process development will be performed on both: selenideand sulfide absorbers. Efficiencies of 15% for selenides and 12% for sulfides arethe goal.
