Outline of Final Research Achievements

We have developed rapid and highly efficient phototermal effect in photothermal film (PTF) with spherical shell-type metallic nanocomposites on a transparent polymer substrate. Particularly, temperature of PTF with spherical shell-type Au nanocomposites can reach 70 ℃ from 25 ℃ by only 100 seconds of artificial solar irradiation. Such a temperature rise exceeds that in asphalt under the midsummer sun light, or that in the black body tape as the highly efficient white light absorber. Furthermore, the output power of the thermoelectric device was enhanced to be one order higher than that without PTF. This result can be applied for the compact and highly-efficient "solar-driven-type thermoelectric conversion devices".
