Open a family to keep every result attached to its sample, method and conditions.
Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
POMOF-functionalised PSCs show higher best and average photovoltaic performance than control devices.
Caveat: Average Voc text appears inconsistent and is separately flagged as uncertain.
p007 · 2.5 Photovoltaic Performance of PSCs · Figure 5; Tables S3,S6 · Linked to 5 structured results
POMOF phosphate groups adsorb and chemically anchor Pb ions, suppressing Pb migration and leakage from degraded PSCs.
Caveat: Figure 6f concentration values are approximate visual estimates.
p009 · 2.6 Mechanism Analysis of Lead Leakage Prevented by POMOF · Figure 6; Figure S25 · Linked to 4 structured results
POMOF improves ambient and thermal operational stability of unencapsulated PSCs.
p008 · 2.5 Photovoltaic Performance of PSCs · Figure 5g,h · Linked to 3 structured results
No BET surface area, pore volume, or gas-sorption porosity measurement was found in the main article or SI text.
Caveat: The material is described as having adjustable aperture, but no quantitative porosity results are provided.
p010 · Conclusion
POMOF functional groups (P=O, C=N) and Mo redox chemistry eliminate Pb0/Pb2+-related defects and reduce trap-assisted recombination.
p003,p006 · 2.2 and 2.4 · Figures 2 and 4 · Linked to 5 structured results
POMOF acts as a heterogeneous nucleation template, accelerates solvent evaporation/crystal growth, and yields larger, better oriented perovskite grains.
p004-p005 · 2.3 Regulation of Perovskite Crystallization With POMOF · Figure 3 · Linked to 3 structured results
Integrating conductive POM clusters into the MOF is proposed to improve electrical conductivity and charge mobility, although no standalone bulk conductivity number is reported.
Caveat: Direct numeric conductivity of pristine POMOF is absent; support is KPFM/C-AFM and qualitative text.
