Ultra-Broadband Polarization-Insensitive MXene-Based Surface Plasmon Resonance Solar Absorber for Solar Thermal Application

Solar energy harvesting is well-known in the past time and solar energy is a superlative source of renewable energy. Researchers have many surface plasmon resonance structures examined with different materials and prevent further losses. In this paper, we proposed MXene-based 2D material with a novel shape of resonator used in solar absorbers. The MXene-based solar absorber effectively captures the sunlight and converts it into heat for its strong optical surface plasmon resonance properties, this solar absorber is used as a solar water heating application. A three-layer solar absorber with a novel shape of resonator layer used of 2D material MXene is constructed to detect a perfect absorption level. The upper layer, or resonator, uses MXene, the centre layer, or dielectric layer, uses SiO2, and the bottom layer, or substrate layer, uses Silver (Ag). With the proposed structure, an average absorption of 94.62
