A near-ideal ultrabroadband absorber composed of Ti, SiO2, Al2O3and TiO2multilayer film is theoretically designed in this work. Our proposed absorber is optimized using a genetic algorithm, and its average absorption is 97% between 400 and 2700 nm at normal incidence. A detailed analysis, based finite difference time domain (FDTD) method, indicates that Fabry–Perot resonance, and the anti-reflection property results in ultrabroadband characteristics. The phase analysis and optical admittance of multilayer absorber further indicate the top dielectric stacks coating shows excellent anti-reflection characteristics. In addition, the ultrabroadband absorber is insensitive to wide incident angle, suggesting that the proposed structure is a promising candidate in application of solar thermal energy harvesting.
