For the uniform illumination, they used semi-transparent thin-film cadmium telluride (Cd-Te), and for the non-uniform illumination, they used semitransparent crystalline silicon (c-Si), which ...

“While a lot of work has been done on perovskite-silicon, perovskite-CIGS, and perovskite-perovskite tandem cells, perovskite-cadmium telluride tandem solar cells are relatively unexplored ...
