- •
A solar-selective absorber with film-coupled tungsten fishnet gratings was proposed.
- •
3D full-wave simulations were performed to investigate the geometric effects.
- •
Broadband light absorption in the visible to near-infrared wavelength range was achieved.
- •
Underlying mechanisms for the enhanced selective absorption of solar light was elucidated.
