In a groundbreaking study published in Results in Engineering, Abdullah Baz from the Department of Computer and Network Engineering at Umm Al-Qura University in Makkah, Saudi Arabia, explores a novel approach to enhancing solar energy absorption using multilayer metal-insulator-metal (MI-MIM) structures. This research could have significant implications for the renewable energy sector, particularly in the development of more efficient solar thermal applications.
The study focuses on two configurations: Gold-MgF2-Gold (GMGSA) and Gold-MgF2-Gold-MgF2-Gold (GMGMGSA). By employing advanced machine learning techniques, the research achieved a remarkable mean squared error (MSE) of 2.8091 × 10−5 and an R² value of 0.998836, indicating a high degree of accuracy in its predictions. The optical response of these structures was meticulously analyzed within the wavelength range of 0.4 μm to 1.6 μm, revealing that the GMGMGSA configuration absorbs an impressive 93.10% of the solar radiation when subjected to the AM 1.5 spectrum, compared to 88.30% for its single-layer counterpart.
Baz emphasizes the commercial potential of these findings, stating, “Our multilayer structure not only enhances absorption rates but also operates efficiently across various angles of incidence, making it a versatile solution for solar thermal applications.” This adaptability is crucial for technologies such as battery-integrated photovoltaic systems (BIPV), commercial solar power (CSP), and solar water heating, all of which are integral to the transition towards sustainable energy production.
The study also highlights the structures’ steady absorption characteristics that remain unaffected by polarization up to a 70° incidence angle, which could simplify the design and implementation of solar collectors in diverse environments. This robustness presents a promising avenue for commercial applications, potentially lowering costs and improving the efficiency of solar energy systems.
As the energy sector increasingly pivots towards renewable sources, innovations like Baz’s multilayer solar harvester could redefine efficiency standards and drive adoption rates. The implications of this research extend beyond academic interest; they signal a future where solar technology becomes more accessible and effective, paving the way for a cleaner energy landscape.
