Expanding Thermal Plasma Chemical Vapour Deposition of ZnO:Al Layers for CIGS Solar Cells

Figure 4

TOF-SIMS depth profiles of ZnO:Al/CdS/CIGS region in (a) a low thermal budget grown device with and (b) a high thermal budget device with . Note that the onset of the constituent elements within CdS and CIGS layers are shifted along the -axis in (b) since the device had a thicker ZnO:Al front contact.
