HTM-FJU-17 improves PSC photovoltaic performance relative to pristine HTM, increasing maximum PCE from 18.32% to 20.34% and average PCE from 17.77% to 19.50%.
Caveat: Performance is in MAPbI3 PSC architecture used here; broader device generality is not shown.

HTM-FJU-17 substantially improves operational, ambient and thermal stability of PSCs compared with pristine HTM.
Caveat: Several stability values are rounded or approximate; raw SI plots/tables were not readable from supplied text.

Adding MOFs into HTM may increase fabrication complexity and cost, so further work is needed to simplify device fabrication.
5 · 3. Results and discussion
FJU-17 acts as a capsule-type additive: Me2NH2+ counterions passivate organic cation vacancies while the anionic framework stabilises oxidised HTM and enhances hole mobility.
Caveat: Passivation mechanism is inferred from XPS/PL/TRPL and comparison with FJU-10; direct tracking of individual ions is indirect.
1 · Abstract · Linked to 4 structured results
The cationic FJU-10 control increases HTM hole mobility but decreases device PCE, supporting the authors' argument that FJU-17's Me2NH2+ vacancy-passivation ability matters in addition to mobility.
Caveat: Full FJU-10 synthetic recipe is not reported in the local main/SI; SI gives a schematic and amount-screening table.

Introducing FJU-17 into HTM improves hole transport and reduces charge recombination in PSCs.
Caveat: Transport metrics are reported for HTM film or full device, not isolated single-crystal MOF conductivity.
