Ultrathin Cu3(HHTT)2 2D c-MOF films function as effective hole transport layers for MA-free ideal-bandgap Pb-Sn perovskite solar cells.
Caveat: Evidence is photovoltaic-device performance and interface spectroscopy, not direct standalone MOF conductivity in this paper.
p001 / article p.3362 · Abstract · Linked to 3 structured results
The layer-by-layer Cu3(HHTT)2 self-assembly route is presented as compatible with large-area and flexible device fabrication.
Caveat: Large-area evidence is ca. 1 cm2 devices; no module-scale roll-to-roll demonstration is reported.
p005-p006 / article p.3366-3367 · Conclusion · Figure S15 · Linked to 3 structured results
The MOF film route is partly specified, but precursor concentrations, post-immersion workup and activation are not reported in the available SI.
Caveat: Recipe completeness for the cMOF film is therefore partial rather than complete.
p003-p004 / SI p.3-p.4 · Synthesis of MOF
The ultrasmooth Cu3(HHTT)2 surface improves perovskite crystallinity, increasing grain size and reducing microstrain compared with NiOx.
Caveat: Causal attribution is inferred by the authors from comparative morphology and XRD.
p004 / article p.3365 · Main text · Figure 2 · Linked to 3 structured results
Cu3(HHTT)2 passivates perovskite interfacial defects, lowering trap density and improving carrier extraction and stability.
Caveat: DFT model uses simplified MAPb0.5Sn0.5I3 surfaces rather than the exact experimental FA/Cs Pb-Sn-Br-I composition.
