Organic photothermoelectric (PTE) materials are promising candidates for various photodetection applications. Herein, we report on poly[Cux(Cu-ett)]:PVDF, which is an excellent polymeric thermoelectric composite, possesses unprecedented PTE properties. The NIR light irradiation on the poly[Cu(x)(Cu-ett)]:PVDF film could induce obvious enhancement in Seebeck coefficient from 52 ± 1.5 to 79 ± 5.0 μV/K. By taking advantage of prominent photothermoelectric effect of poly[Cu(x)(Cu-ett)]:PVDF, an unprecedented voltage of 12 mV was obtained. This excellent performance enables its promising applications in electricity generation from solar energy and NIR detection to a wide range of light intensities ranging from 1.7 mW/cm(2) to 17 W/cm(2).
有机光热电（PTE）材料是各种光检测应用的有前途的候选材料。在此，我们报道了聚[Cux（Cu-ett）]：PVDF，它是一种优异的聚合物热电复合材料，具有前所未有的PTE性能。对聚[Cu(x)(Cu-ett)]:PVDF薄膜进行近红外光照射可使塞贝克系数从52±1.5显著提高到79±5.0 μV/K。利用聚[Cu(x)(Cu-ett)]:PVDF突出的光热电效应，获得了前所未有的12 mV电压。这种优异的性能使其在从太阳能发电和近红外检测到1.7 mW/cm(2)至17 W/cm(2)的广泛光强范围内具有广阔的应用前景。
