At present, solar energy is widely used as a kind of clean energy. The main solar radiation
range under AM 1.5 is about 300 ~ 3000 nm. In this paper, we designed an efficient, ultra-…

Electromagnetic wave absorbers with very long absorption spectra have become an important
target for optoelectronic materials and technology. In this paper, we propose a titan-based …

Nowadays, solar energy is considered one of the most clean energy sources. In addition,
the data from the literature tell us that its main radiation bandwidth is approximately 295–2500 …

Solar energy as an inexhaustible source of clean energy has attracted more and more
attention. As an important way to collect source of energy, solar absorber is widely reported and …

In the study of modern optics, the work of terahertz metamaterial absorbers is mostly multi-band
perfect absorbers and ultra-wideband perfect absorbers. In contrast, in practical …

By means of critical coupling and impedance matching theory, we have numerically simulated
the perfect absorption of monolayer graphene. Through the critical coupling effect and …

In this paper, we present a dual-band metamaterial absorber for graphene surface plasmon
resonance at terahertz frequency. We use the finite difference time domain (FDTD) method …

In this paper, we have utilized finite difference time domain (FDTD) method to investigate
the solar energy absorption of hybrid solar cells (HSCs) with trapezoid-pyramidal structure (TPs…

The range of solar radiation observed on Earth is about 295–2500 nm. Designing the
absorber within this range allows it to obtain as long an absorption band as possible to help …

In this paper, we designed a three-band narrowband perfect absorber based on bulk Dirac
semi-metallic (BDS) metamaterials. The absorber consists of a hollow Dirac semi-metallic …
