Solar Thermal Absorber Using Fe₂O₃‐SnSe₂‐Ti‐Layered Structure Based on Graphene Material

Abstract

In solar energy systems, manufacturing solar absorbers also includes an important section. A one‐perfect design is constructed in three layers to develop a good solar absorption rate and a graphene layer is used in this developed structure. Titanium (Ti) is in the base layer, Stannic selenide (SnSe2) is in the substrate layer, and Ferric Oxide (Fe2O3) is a resonator. The absorption rates can be presented between the overall wavelength range of 0.2–3 µm and divided into three segments. The absorption percentage is above 90% for 2800 nm, more than 95% is in the half region of 0.2–2 µm (1800 nm), and the perfect absorption result of 97% is between 0.2 and 1.5 µm (1300 nm), respectively. AM 1.5 section and graphene results can be calculated by using the numerical equations. To indicate the fewer and greater parameters of the present number, parameter variation sections can be presented. According to the symmetrical design of the developed structure, TE and TM results are almost identical and can be configured in color representation. The greater the amount of light intensity, the greater the number of absorption rates. The polarization can be checked between 0° and 50° changes.
