Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Adding Zn2(ZnTCPP) MONs to P3HT-PCBM roughly doubles champion PCE from 2.67% to 5.20% and improves Jsc, Voc and FF under optimised processing.
Caveat: Application result from an older P3HT-PCBM model system; not a standalone MOF conductivity measurement.
1,4 · Abstract; 2.2 Device fabrication · Table S1 · Linked to 5 structured results
No first-hand gas sorption or porosity measurements for Zn2(ZnTCPP) MONs were reported in the supplied main article or SI.
Caveat: The introduction discusses high surface area generally for MONs, but no BET or pore-size data appear in the supplied documents.
1-37 · Full SI review
The nanoscale monolayer morphology is required for functional devices; bulk unexfoliated MOF controls did not function.
Caveat: The non-function of bulk-MOF devices is attributed to short-circuiting by micron-sized MOFs; no numeric device data were reported for this failed control.
4,6 · 2.2 Device fabrication; 3 Discussion · Linked to 3 structured results
Zn2(ZnTCPP) MONs act as a template or surface that increases crystalline P3HT fraction, reduces PCBM aggregate/domain size, and improves charge transport in the ternary active layer.
Caveat: The templating/barrier mechanism is inferred from GI-WAXS, AFM and transport correlations rather than directly imaged molecular templating.
7 · 4 Conclusions · Fig. 6 · Linked to 4 structured results
The MON LUMO lies between P3HT and PCBM and may permit an energy cascade without introducing charge traps, but transient absorption did not show clear new charge-transfer features.
Caveat: The paper explicitly states that charge transfer to MONs either does not happen or occurs faster than the experimental setup can resolve.
