By integrating OLEDs with solar cells, ambient‐light reflection as low as 1.4% (even superior to that achieved with polarizers) can be achieved without compromising the EL efficiency. for high‐contrast display applications; Furthermore, in such a device, the incident photon energy and a portion of the OLED emission that does not get outside of the device can be recycled by conversion to electrical power. These features, we believe, make this technique attractive for high‐contrast display applications and portable/mobile electronics that are power aware.
