   Sammanfattning : Two identified setbacks for CIGS based devices in order to obtain higher efficiency are parasitic absorption in the window layer structure and losses in open-circuit voltage due to bad interfaces. This study investigated how the performance of the solar cell is affected by depositing intrinsic ZnO (i-ZnO) and ZnMgO with atomic layer deposition (ALD) instead of the conventional sputtering.
