標題: | Organic Light-Emitting Devices Integrated with Solar Cells: High Contrast and Energy Recycling | 作者: | Chih-Jen Yang Ting-Yi Cho Chun-Liang Lin CHUNG-CHIH WU |

Furthermore, in such a configuration, the photon energies of the incident ambient light and the portion of OLED emission not getting outside of the device can be recycled into useful electrical power via the photovoltaic action, instead of being totally wasted as in other reported contrast-enhancement techniques. These features, the authors believe, shall make this technique attractive for high-contrast display applications and portable/mobile electronics that are highly power aware. © 2007 American Institute of Physics. |
