HIGH-EFFICIENCY ELECTRICITY GENERATION USING NANOANTENNAS FOR SOLAR AND INFRARED RADIATION

Annotation: Nanoantennas provide a transformative approach to electricity generation by harnessing solar and infrared radiation across a wide electromagnetic spectrum, surpassing the capabilities of conventional photovoltaic systems. This study evaluates their performance through a detailed theoretical analysis and finite-difference time-domain Webhook (FDTD) simulations, focusing on graphene-based designs and broadband configurations. Results indicate an energy conversion efficiency of up to 42% under optimized conditions, a significant improvement over silicon-based cells. Challenges such as fabrication complexity and rectification losses are analyzed, with strategies proposed for scalable deployment. These findings highlight nanoantennas’ potential to advance renewable energy solutions.
