Author interpretations and caveats

Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.

Application RelevanceSupport assessment: High

Among the simulated MOF HTLs, Cu3(HHTP) gives the best baseline 300 K PCE, closely followed by Sr-MoF.

Caveat: The section text has a likely typo of 25.26% for Cu3(HHTP), while abstract, Table 1 and conclusion report 24.26%.

p014 · Conclusion · Linked to 2 structured results

CaveatSupport assessment: High

The paper is a SCAPS-1D computational modelling study and reports no first-hand MOF or device synthesis route.

Caveat: SI only contains equations, device schematic, model input tables and references.

p002 · Computational Methodology and Device Modeling

CaveatSupport assessment: High

SCAPS-1D results should be treated as guiding predictions because 1D modelling omits grain boundaries, lateral inhomogeneity, ion migration, thermal degradation and detailed optical effects.

Caveat: This limitation comes from the authors theoretical-boundaries section.

Structure Property LinkSupport assessment: Medium

MOF/FASnI2Br band alignment is used to explain the PCE ranking: favourable Cu3(HHTP) and Sr-MoF offsets reduce recombination, while Cu-MoF has the poorest alignment.

Caveat: Band offsets are calculated from model electron affinities and bandgaps; several CBO values were read from Figure 6.

Transport MechanismSupport assessment: High

Increasing FASnI2Br defect density sharply decreases carrier lifetime and diffusion length, indicating defect-assisted recombination limits transport.

Caveat: Values are simulated and text-reported, not experimental measurements.
