Abstract
We investigated the impact of incorporating 2% oxygen during intrinsic ZnO sputtering on the efficiency of Cu(In, Ga)Se-2 solar cells. The added oxygen not only reduced the optical absorption loss of the Al-doped ZnO overlaying layer but also improved the electronic properties of the underlying CdS/Cu(In, Ga)Se-2 by increasing carrier density, lowering defect level, and increasing diffusion length, eventually enhancing JSC, VOC, and fill factor. It was found that the Na doping concentration was significantly increased around the CdS/Cu(In, Ga)Se-2 junction due to the plasma-activated oxygen. The improved electronic properties are better explained by the increased Na concentration than simply the oxygen-related defect passivation. (C) 2014 AIP Publishing LLC.
