“…Inspired by the idea of slowlight waveguide, a lot of researchers have considered using hyperbolic metamaterial to enhance the absorption of 2D materials and propose broadband absorber, although most of the reports are focused on mid infrared and terahertz band [94][95][96][97][98][99]. Not long ago, in the visible band, Pourmand et al [85] designed and investigated a broadband absorber based on the hyperbolic metamaterial, which consists of periodically arranged gold and methyl ammonium lead iodide (MAPbI 3 ) nanolayers, as shown in figure 8. This absorber exhibits a nearly-perfect optical absorption from 400 to 800 nm for (CH 3 NH 3 )PbI 3 [85] Taking advantage of the hyperbolic metamaterial 400-800 Almost 100% a wide range of incidence angles under the TM-polarized incidence.…”

Moreover, the uniformity of broadband absorption can be further improved by replacing the top Au-nanolayer with a porous Au-nanolayer.…”

Two-dimensional (2D) materials, due to their unique electronic, optical and structural properties, have attracted extensive attention of researchers in the world. However, most of 2D materials have low optical absorption efficiencies in the visible and near-infrared regimes, which leads to the weak light–matter interaction and limits their further applications in optoelectronic devices. Thus, enhancing the light–matter interaction of various 2D materials in the visible and near-infrared regimes, has been a key topic for many optoelectronic equipment and related applications. In this topical review, we summarized the recent developments of the 2D materials-based optical absorbers in the visible and near infrared regimes, focusing mainly on the methods and relevant physical mechanisms of several typical perfect absorbers, such as narrowband perfect absorbers, dual-band perfect absorbers, and broadband perfect absorbers. Finally, several prospective research directions from our perspectives are presented at the end.
