Expanding Thermal Plasma Chemical Vapour Deposition of ZnO:Al Layers for CIGS Solar Cells
Variation of short circuit density (), fill factor (FF), conversion efficiency (), open circuit voltage (), series resistance (), and shunt resistance () as a function of ZnO:Al layer thickness for (a) low thermal budget and (b) high thermal budget conditions. Solar cell parameters of the reference cell are indicated by the open triangles. Dashed lines are used as a guide to the eye.
