Transparent conductive oxides are an important material in the photovoltaic and semiconductor industry. In the past years, Hydrogen doped Indium Oxide (IOH) has shown outstanding electrical and optical properties compared to Aluminum doped Zinc Oxide (AZO). Therefore, it has a high potential as a transparent front contact in CIGS solar cells and modules where this material is commonly used. In this project, we are investigating the properties of pulsed DC-sputtered IOH before and after an annealing on varying substrate layers to successfully implement the material in CIGS. This will help to improve the efficiency of the devices due to a better management of the sunlight.
