In this paper the researchers utilize the wide-bandgap CsPbI2Br semiconductor and narrow-bandgap PM6:Y6-BO blend to fabricate perovskite/organic tandem solar cells with an efficiency of 21.1% and a very small tandem open-circuit voltage loss of 0.06 V.

The photon absorption rate distribution of polyTPD and PBDB-T-Si based TSCs were simulated using the transfer-matrix model via SETFOS (version number: SETFOS 5.1)
