| Application: | COi8DFIC is primarily utilized as a non-fullerene acceptor in OPV devices. It exhibits a broad absorption spectrum, enabling it to absorb light across a wide range of wavelengths, including the visible and near-infrared regions. This property allows for efficient utilization of a broader range of solar radiation, enhancing the light-harvesting capability of the OPV device. COi8DFIC can be employed as the electron transport material in OFET devices. |
| Application: | COi8DFIC or O6T-4F is a highly efficient, n-type, low-bandgap nonfullerene acceptor with strong NIR absorption In a recent study, COi8DFIC or O6T-4F was selected in a Tandem cell by computer assited design and gave a record PCE of 17.3% for fabricated organic solar cells. Tandem Cell Device performance: ITO/ZnO/PFN-Br/PBDB-T:F-M Voc=1.642 V Jsc=14.35 mA/cm2 FF=73.7% PCE=17.3% COi8DFIC or O6T-4F is frequently selected to blend with a narrow-bandgap donor material and another narrow bandgap acceptor material to fabricate ternary organic solar cells. The PTB7-Th:COi8DFIC:PC71BM ternary cells offered a PCE of 14.08%. By further adopting a post-annealing process, an outstanding PCE of 14.62% can be achieved. Furthermore, the device utilizing COi8DFIC exhibited a good thermal stability with PCEs over 13.5% in a wide temperature range (70-160 °C). Device structure: ITO/ZnO/PTB7-Th:COi8DFIC: • Before annealing Voc=0.702 V Jsc=27.74 mA/cm2 FF=0.701 PCE=13.65% • After annealing at 80°C Voc=0.727 V Jsc=27.39 mA/cm2 FF=0.734 PCE=14.62% |
| Application: | COi8DFIC, an efficient non-fullerene acceptor material, has a strong near-infrared range (NIR) light absorption. It can be used as an n-type small molecule acceptor material for the fabrication of polymeric solar cells. |
