Hexyl-derivatized poly(3,4-ethylenedioxyselenophene) (PEDOS-C6) are investigated with optical and photo-thermo-electrical properties by external electrical stimuli. These properties are clearly demonstrated by precisely controlling the doping state and the surface morphology from applying potential of the flexible polymer films. Especially, the doped polymer film at -0.1 V reveals the highest photothermal conversion efficiency and a power factor of 42.5% and 354.7 μW m−1 K−2, respectively. Efficient visible to NIR absorption, photon to heat, and heat to electric conversion has been realized in one transparent film that could benefit in exploiting invisible NIR sensors, multifunctional film displays, day and night vision display, invisible NIR sensors, optical attenuators, photodynamic theragnosis, and thermoelectric devices. |
