Perovskite-CIGS tandem solar cells have technical potential to achieve 26.69% efficiency

A Dutch and U. S. research team performed optical and electrical simulations to understand loss mechanisms in two terminal (2T) tandem cells based on perovskite and commercially available copper-indium-gallium-selenide (CIGS) cells, and subsequently established a roadmap to increase efficiency via four key modifications. A research team led by the Delft University of Technology in the Netherlands has outlined a roadmap for the optimization of monolithic perovskite/CIGS tandem solar cells and has found these PV devices may achieve a practical efficiency limit of 26. 69%. Using TCAD Sentaurus and ...
