Semitransparent Blue, Green, and Red Organic Solar Cells Using Color Filtering Electrodes |
| 초록 |
Colorful, semitransparent organic photovoltaics (OPVs) are increasing in demand due to their applicability in aesthetically-fashioned power-generating windows. The traditional method of generating different colors in OPVs has been through employing different active materials exhibiting distinct absorption spectra. This can complicate fabrication processes and cause deviations in device performance among differently colored OPVs. We demonstrate semitransparent and colorful OPVs with a single broadband-absorbing active material using Ag-TiOx-Ag color filters (CFs). The CF enables the OPV to transmit spectrally pure colors and allows the colors to be freely tuned without disturbing the charge transport properties such that the device performance stays consistent. The CF not only functions as an effective electrode but as a mirror for light outside of the spectral transparency window. We show that CF-integrated OPVs generate more short circuit current compared to a transparent OPV. |
