Abstract Scope |
We have developed a Photothermal Solar Tunnel Radiator for direct solar harvesting via transparent photothermal films containing plasmonic Fe3O4@Cu2-xS nanoparticles. The transparent substrates are arranged in parallel within a longitudinal tunnel enclosure. Captured sunlight is channeled through these substrates via a solar dome, where the photothermal coatings efficiently convert photons into heat, raising the substrate surface temperature. Acting as a utility thermal radiator, the heated substrates then dissipate thermal energy into the building space without requiring external power sources. At an ambient temperature of –10°C, the internal temperature of the PSTR photothermally rose to 40°C, demonstrating significant energy generation. This direct solar harvesting mechanism signifies a notable advancement in utilizing natural sunlight for energy-neutral systems with enhanced efficiency. We present the synthesis and characterization of Fe3O4@Cu2-xS nanoparticles alongside the analysis of photothermal thin films. We report the correlations between photothermal heating and the optical absorptions of these thin films. |
