Customer ServiceDouble heterojunctions passivate dual interfaces and mitigate ion migration. Rigid and flexible PSCs exhibit an enhanced PCE of 24.08 % and 21.58 %, respectively. The release of residual stress enhances the mechanical stability of FPSCs. Perovskite solar cells (PSCs) have demonstrated considerable potential as a promising photovoltaic technology.
The light intensity dependence of VOC curves were also measured (Fig. S14b). The double-heterojunction device exhibits a lower slope (1.128 kT/q) in comparison to the pristine device (1.515 kT/q), which suggests that the 2D/3D/2D perovskite double heterojunctions can effectively suppress defect-induced recombination.
Integrating 2D/3D heterojunctions at the buried bottom interface is desirable too, but has rarely been reported so far 17, 18, 19. The primary difficulty here is to avoid the dissolution of the pre-deposited 2D layer or the organic ammonium-based ligands during the subsequent 3D perovskite deposition 17, 18, 19.
Consistent with the results obtained from the rigid devices, the double-heterojunction FPSCs exhibit higher average photovoltaic parameters and better reproducibility, proving the universality of the method (Fig. S19 and Tables S8 and S9). The mechanical stability of FPSCs is a prerequisite for their commercial application.
To resolve the challenge of 2D/3D heterojunction formation at the bottom of the perovskite film, we mixed the 4-hydroxybenzylamine (HBzA) ligand into the 2PACz SAM solution, which was then coated onto the ITO bottom electrode.
The optimal double-heterojunction FPSCs achieve a PCE of 21.58 % under reverse scan, while the optimal pristine device only delivers a PCE of 18.76 % (Fig. 5 a and Table S7). The double-heterojunction FPSCs obtain a higher integrated JSC value (23.11 mA/cm 2) than the pristine counterpart (22.88 mA/cm 2) (Fig. 5 b).
