Influence of the Subcell Properties on the Fill Factor of Two-Terminal Perovskite-Silicon Tandem Solar Cells

Christophe Ballif, Mathieu Gérard Boccard

The performance of a tandem solar cell depends on the performance of its constituting subcells. Although this dependency is theoretically straightforward for open-circuit voltage (V-oc) and short-circuit current, it is indirect for fill factor (FF) and thu ...

Thermodynamically stabilized beta-CsPbI3-based perovskite solar cells with efficiencies > 18%

Mohammad Ibrahim Dar, Yang Li, Xiaoyan Wang, Ying Yang, Xingyu Gao

Although beta-CsPbI3 has a bandgap favorable for application in tandem solar cells, depositing and stabilizing beta-CsPbI3 experimentally has remained a challenge. We obtained highly crystalline beta-CsPbI3 films with an extended spectral response and enha ...
