In this manuscript, various structures are investigated to utilize more solar energy. From that two structures are discussed in terms of their applications. The optimized structure prevents highly efficient solar absorber structure with the solar spectral range of 200 nm–3000 nm wavelength. The structures investigated here are disk-like structures fixed on a flat surface made up of Carbon nanotube (CNT) and Titanium Carbide (TiC) is the active layer or absorber layer. TiC and CNT are the main materials that are utilized to study this solar absorber. Absorption achieved by the structure over the full spectral range is more than 93% where average absorption is 97.35% (200 nm–3000 nm). The maximum absorption achieved here is 99.89% with the wavelength of 2210 nm–2260 nm range and the minimum absorption is 92.75% with 2590 nm (MIR region). Here the achieved absorption is 97.06%, 97.81%, 97.36% and 97.26% for UV, VIS, NIR and MIR respectively. Due to this, it is applicable in various ways like a solar heater for air and water, solar induction, etc.
