摘要

Sustainable energy solutions are required since conventional energy sources, such as fossil fuels, cause environmental degradation and resource depletion. In the present study, we have investigated the graphene-based metamaterial solar absorber (GBMSA) for designing a wide range of solar energy harvesting systems. In the 200–4000 nm range, the average absorption of GBMSA is 91.09%, and its reflection is 8.9% with 8.15 × 10−6 transmission. UV has the lowest absorption (88.41%) and NIR the highest (92.32%). In the MIR and VIS regions, the average absorption approaches 90%, with GBMSA reflecting the remaining energy. Transmission is nearly zero across the entire solar spectrum. With an average R2 value of 90% and a mean squared error of 2.23 × 10−6, the machine learning method for predicting the performance of the GBMSA cuts modeling time from 56 to 7 h. The GBMSA is polarization-insensitive to TM and TE waves, maintaining over 50% absorptance up to a 70° incident angle, making it appropriate for various light sources. With these findings, the GBMSA discovers effective applications in solar air and water heating, industrial heating, and solar induction systems.
