Large-scale, transferable and double-sided metasurface absorber for the visible to near-infrared spectrum
Source abstract
Abstract
Metasurface absorbers with broad-band, high absorption in the visible-near-infrared range can efficiently absorb solar energy, showing great potential in applications such as photothermal devices, radiative cooling, and stray light elimination. Here, we design and fabricate a metasurface absorber in the visible to near-infrared spectrum with high absorption, high yield and double-sided operation. The proposed metasurface absorber has a simple structure and manufacturing process, with a base consisting of a polystyrene microsphere array prepared by colloidal self-assembly, and a top layer made of chromium deposited by magnetron sputtering . Through the combined effects of surface plasmon resonance and magnetic polaritons , the metasurface absorber achieves average absorption of 84% on the front side and 91% on the back side within the 400 to 2500 nm spectrum. Additionally, due to its simple nanostructure , our metasurface absorber can be flexibly transferred to surfaces of various shapes. Our research provides a practical solution for achieving efficient solar energy absorption using metasurface absorbers.
