Abstract Scope |
This study explores an innovative solution to the growing demand for sustainable energy by harvesting indoor light for energy generation through photothermal transparent thin films and photovoltaic (PV) systems. By utilizing plasmonic Fe₃O₄@Cu₂₋ₓS nanoparticles with unique UV and IR absorption properties, we create a dual-mode system that generates heat for heating modes and electricity for cooling modes. The transparent thin films efficiently transmit diffused light, converting it into thermal energy via localized surface plasmon resonance (LSPR). At the same time, silicon PV systems capture photons emitted by indoor LED lights and convert them into electricity, ensuring consistent, weather-independent energy generation. Experimental results show positive energy outcomes, with photothermal systems raising temperatures up to 54.8°C and indoor PV systems generating electricity from LED lighting operational 24/7. This work paves the way for integrating renewable energy solutions into energy-neutral architectural designs, providing a promising future for sustainable building technologies. |
