However, there’s a way to get around that—with the magic of tandem solar cells ... a fact that not every electron excited in the cell structure contributes to current flow.

“All-perovskite tandem solar cells constructed by wide/narrow bandgap ... solution post-treatment to form 2D/3D heterojunction structure,” Tan said. “However, the 2D perovskite obtained ...

“Besides, the inorganic CuSCN is also applied in perovskite/silicon tandem solar cells for the first time ... resulting in a different device structure from that of a common and classic p ...
