Abstract :
The performance of ultra-thin CIGS solar cells can be greatly improved by the addition of multilayer anti-reflective coatings. They serve as excellent light traps in the red and near infra-red regions, thereby enhancing the total efficiency of the solar cell. In this study, multiple layer AR coatings were optimized on ultra-thin CIGS solar cells and a reduction in reflectance was observed. Different materials were explored in order to decrease the overall reflectance of the solar cell without increasing the complexity of the cell.
