a-Si/c-Si BMBF network project
"basic research and technology of amorphous/crystalline heterojunction solar cells"
Motivation / Aims
low temperature processes for silicon solar cells (T<200°C)
- efficiency > 17 % (CZ)
- efficiency > 14 % (FZ)
- control of interface recombination
- efficiency only limided by quality of c-Si absorber
