Abstract (Englisch)

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 CdS 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 simplicified process management will reduce production costs for these highly efficient and lox-toxic PV modules. Material and process development will be performed on both: selenide and sulfide absorbers. Efficiencies of 15% for selenides and 12% for sulfides are the goal.
