A Device architecture of TSC with perovskite front sub-cell (varied bandgap) and organic rear sub-cell (1.46 eV). B Theoretical and practical current-density limits of TSCs based on the present high-efficient rear cell (~1.46 eV, D18-Cl:L8-BO) with different front cell bandgaps. For practical current-densities, we take the achievable thickness of high-quality perovskite film and organic active layer into account (Table S4). C The corresponding theoretical and practical efficiency limits of TSCs. We assume that the VOC,TSC is the sum of the record VOC,PSC, and VOC,OSC, and the FFTSC is 80% (Table S4). For practical limits in a real device, the maximum reported thicknesses of high-quality perovskite film and organic active layer from literature was considered.
