Description
Summary:•Reviewing different types of material for the window layer.•Analyzing various deposition methods of the window layer.•Discussing material, electrical, and optical properties.•Proposing new material combination for the window layer. Several factors, particularly the material of the window layer, contribute to the efficiency of CIGS solar cells. To optimize light absorption and reduce energy losses, it is critical to select the appropriate material for the window layer development. Thus, the main emphasis of this review is on the development of window layers, covering fundamental concepts, synthesis techniques, characterization methods, and optimization strategies. Metal oxides and doped metal oxides are critical materials for optimizing charge carrier flow, minimizing energy loss, and elevating sunlight transmission to the CIGS absorber. Despite tremendous progress, difficulties such as increased conductivity, transparency, stability, and cost-effectiveness remain. Discovering novel materials, specific combinations, and improved deposition techniques offers further details on the structure-property relationships of window layers. Addressing these difficulties is critical to improving the performance of CIGS solar cells, which are now approximately 23.6 % efficient. These enhancements are critical for progressing sustainable energy solutions. [Display omitted]
