A Comparative Study of (Cd,Zn)S Buffer Layers for Cu(In,Ga)Se₂ Solar Panels Fabricated by Chemical Bath and Surface Deposition Methods

Scale-up to large-area Cu(In, Ga)Se ₂ (CIGS) solar panels is proving to be much more complicated than expected. Particularly, the non-vacuum wet-chemical buffer layer formation step has remained a challenge and has acted as a bottleneck in industrial implementations for mass-production. This technical note deals with the...
