|---|---|---|---|---|---|
| PM6: L8-BO | PDINN | 0.877 | 26.10 (25.75) | 80.17 | 18.35 |
| PDINN: 5 wt% 2BN-4 | 0.880 | 26.85 (26.02) | 80.60 | 19.04 | |
| PDINN: 5 wt% 2BN-5 | 0.883 | 26.92 (26.09) | 80.20 | 19.06 | |
| PDINN: 5 wt% 2BN-6 | 0.885 | 27.14 (26.15) | 81.61 | 19.60 |
The PDINN electron-transporting layer either without or with 5 wt% B–N compound.
Open-circuit voltage (VOC).
The measured JSC values from J–V curves and the integrated JSC values from the EQE spectra.
The fill factor (FF).
The power conversion efficiency (PCE) was calculated as PCE = (VOC × JSC × FF)/Pin, where Pin is the incident light power density, typically set to 100 mW cm−2 under standard AM 1.5 G illumination conditions.
