Thin films made of metallic nanoparticles can exhibit strong photothermal effects on near-infrared light irradiation and also show unique semi-directional heat transport features due to quasi-ballistic thermal transport from the localized surface hot spots. In this work, we incorporate this feature into a new design on greenhouse coverage. The thin films were placed on the interior surface in winter and outside in summer relative to the greenhouse coverage layer. The simulation results show that the different placements of the thin films present a substantial ability to control solar heat gain with a range between about 0.2 and 0.6 with a stable Photosynthetically active radiation (PAR) transmittance of 0.32. The variation of solar heat gains of the system may meet the operational energy saving needs without compensating solar radiation for the plant growth.
