Photovoltaic parameters of the OSCs with or without any treatment under 1 sun illumination.
| BHJ | condition | Voc (V) | Jsc (mA cm–2) | FF (%) | PCE (%) | Jsc-EQE (mA cm–2) |
|---|---|---|---|---|---|---|
| PM6:Y6 a) | As-cast | 0.825 | 24.49 | 65.81 | 13.30 (13.04±0.31) | 23.37 |
| PM6:Y6 b) | Optimized | 0.834 | 26.45 | 72.85 | 16.08 (15.80±0.28) | 25.63 |
| PM6:Y6-eC6-BO a) | As-cast | 0.846 | 26.44 | 77.42 | 17.33 (17.07±0.25) | 25.30 |
| PM6:Y6-eC6-BO b) | Optimized | 0.841 | 26.32 | 75.72 | 16.76 (16.55±0.23) | 25.21 |
a) The OSC devices are processed without any treatment.
b) The devices are optimized by 0.5% CN (volume ratio) and 100 °C thermal annealing of 10 min. The data shown in brackets are averaged from over 10 devices and Jsc-EQE is the photocurrent integrated from the EQE spectrum.
