A SEM cross-section image of a TSC. B J-V characteristics of the champion CsPbI2Br/D18-Cl:L8-BO P-O-TSCs with MoOx-based and PEDOT:F-based ICLs. C Corresponding EQE spectra. Reflection (denoted as 1-R) and sum (total EQE of individual sub-cells) curves are also presented. D Statistical diagram of the VOC values obtained from the reported P-O-TSCs. E, F VOC distributions and JSC distributions of 25 devices over three batches. G J-V characteristics of the champion P-O-TSCs utilizing PEDOT:F, incorporating various organic rear cells (D18-Cl:L8-BO and D18-Cl:L8-BO:BTP-eC9). H J-V characteristics of the champion P-O-TSCs utilizing MoOx and PEDOT:F, incorporating highly efficient PM6:L8-BO:BTP-eC9 organic rear cells with a narrower bandgap of 1.41 eV. I Efficiency distributions of tandems with D18-Cl:L8-BO:BTP-eC9 and PM6:L8-BO:BTP-eC9 rear cells.
