Summary: This study demonstrates a 2-terminal monolithic perovskite/organic tandem solar cell (TSC) configuration, which incorporates wide bandgap all-inorganic perovskites as front cell absorber and organic blend as rear cell absorber, to extend the absorption range of organic solar cells (OSCs) into high-energy photon region. By optimizing the electron transporting layer and interface structure, high open-circuit voltage and charge transport efficiency are achieved. The remarkable power conversion efficiency (PCE) obtained in this study highlights the potential of this strategy to improve the efficiency of OSCs.

Summary: This work presents the use of Sn-Pb binary metal inorganic perovskites as narrow-bandgap absorbers for integrated 4-terminal all-inorganic perovskite tandem solar cells. Through tuning the Sn-Pb and I-Br contents, a series of Sn-Pb binary metal CsPb1-xSnxI3-yBry inorganic perovskites with tunable bandgaps ranging from 1.28 to 1.45 eV were synthesized. The resulting tandem solar cell achieved a remarkable power conversion efficiency over 18% and a high open-circuit voltage of 2.13 V, demonstrating the potential for solar fuel production.
