Design and Development of Surface Plasmon Resonance‑Based Solar Thermal Absorber Using Fe‑Ti‑SnSe2 Multilayered Approach for Thermal Heating Application

This proposed surface plasmon resonance design (solar absorber) with constructed materials of iron (Fe), titanium (Ti), and tin selenide (SnSe2) with the used layers of resonator design (top), substrate layer (middle), and ground (bottom). The radiated power exhibited in this design for overall bandwidth is 2800 nm for the wavelength range explores 0.2 and 3 µm with 93.2%. The other two wavelength division on the overall wavelength is 1080 nm (1.2–2.8 µm), and 2080 nm (0.2–2.28 µm) with absorption configurations of 97.24% and 95.82%, respectively. According to the highest generated absorption by the highest wavelength points (micrometers) of 0.23, 0.49, 0.75, and 1.85, we can check the resulted absorptions on the overall range. To describe the specific presentation for this design, multiple sections have been used such as the Design and Parameter section for the construction steps and parameter assignments, the Results and Analysis section to exhibit the resulted absorptions in various parameter changes, and the Conclusion section. The proposed type of absorber can be applied in some heating systems of water, turbines, tubs, and so on. Moreover, compared to the other forms of electricity generation, this solar design can be more reliable to reduce home electric bills properly.
