In recent years, as a renewable clean energy with many excellent characteristics, solar energy has been widely concerned. In this paper, we propose an ultra-broadband solar absorber based on metal tungsten and semiconductor GaAs structure. A multilayer metal semiconductor composite structure composed of W-Ti-GaAs three-layer films and GaAs gratings is proposed. The finite difference time domain method is used to simulate the performance of the proposed model. High efficiency surface plasmon resonance is excited by adjusting the geometric parameters, and the broadband absorption of up to 2,350 nm in 500–2850 nm is realized. The spectrum of the structure can be changed by adjusting the geometric parameters to meet different needs. The proposed absorber has good oblique incidence characteristics (0–60°) and high short-circuit current characteristics. The geometry of the absorber is clear, easy to manufacture, and has good photoelectric performance. It can realize solar energy collection, light heat conversion, high sensitive sensing and other functions.
Introduction
From the beginning of the 21st century, with the improvement of people’s living standards, there are more and more kinds of household appliances, and the demand for traditional fossil energy is also increasing, which is in contradiction with the characteristics of non-renewable resources. According to the existing data, if energy consumption can not be controlled before the end of this century, oil and natural gas energy will be exhausted, and coal reserves will be exhausted. With the decrease of these conventional non-renewable resources, how to effectively and reasonably use conventional energy, and develop and utilize new energy, especially renewable energy, is a major event in front of all mankind (Xiao et al., 2017; Tang et al., 2018; Cai et al., 2019; Sivák et al., 2020; Xie et al., 2020; Zhao et al., 2021).
Among all kinds of energy, as a renewable energy, solar energy is considered to be the most potential energy, because it is inexhaustible, reliable, less pollution and so on. As an important energy collection device, solar absorber has attracted more and more attention in recent years (Li et al., 2016; Chen et al., 2019a; Xiao et al., 2019; Li et al., 2020a; Roostaei et al., 2021). For an ideal absorber, it must have high efficiency light absorption and many other excellent physical properties, such as polarization stability and tunability (Li et al., 2020b; Wu et al., 2020; Yi et al., 2020; Chen et al., 2021a; Jiang et al., 2021a; Li et al., 2021a; Li et al., 2021b; Li-Ying et al., 2021; Zhou et al., 2021). However, the existing absorbers are generally limited by low temperature tolerance, low light absorption efficiency and materials (Chen et al., 2020; Chen et al., 2021b; Jiang et al., 2021b; Wang et al., 2021; Zhang et al., 2021). Therefore, a new type of broadband solar energy which can solve the above problems needs to be proposed. According to the actual situation of solar radiation in the range of 295–2,500 nm, the key to realize the efficient utilization of solar energy is to design a solar device which can match the band perfectly.
The research on broadband absorber has been carried out for many years in the world, and it has been used in solar cells, solar heating devices and photothermal converters (Liu et al., 2017; Keshavarz and Vafapour, 2019; Yu et al., 2020; Chen et al., 2021c; Su et al., 2021). For the design and improvement of broadband absorber, we should pay attention to the following aspects: the first is to select the appropriate material. Traditional precious metal materials such as gold and silver were used in the original broadband absorbers. However, due to its high cost and poor high temperature resistance, people began to pay attention to high melting point materials such as titanium nitride. They not only have high melting point, but also can excite effective plasmon. Secondly, the nanostructure design of broadband absorber is also very important. The multi-layer metal-insulator structure was first used, and then turned to simpler MIM or IMI nanostructures. Finally, the working area of broadband absorber, especially from ultraviolet to near-infrared, has been studied and improved. Efforts in these directions are to obtain ideal broadband absorbers for practical applications. For instance, Lei proposed an ultra-broadband absorber based on a thin metamaterial nanostructure composed of Ti-SiO2 cubes and Al bottom film. The proposed structure can achieve nearly perfect absorption with an average absorbance of 97% from 354 to 1,066 nm (Lei et al., 2018). Huang proposed a broadband absorber with near-unity absorption in the terahertz regime based on a target-patterned graphene sheet, the absorption bandwidth (more than 90%) is 1.57 THz with a central frequency of 1.83 THz under normal incidence (Huang et al., 2018). Although the characteristics of these absorbers are superior enough, their complex nanostructures and a variety of complex materials make the proposed absorbers difficult to apply. Therefore, an absorber with simple structure and excellent high absorptivity should be proposed.
In this paper, we propose a broadband solar absorber composed of W-Ti-GaAs three-layer thin film and GaAs grating, as shown in Figure 1. The proposed structure uses W metal as the substrate and GaAs semiconductor grating as the auxiliary structure. There is a layer of metal Ti between the w base and the GaAs film, and the top layer is a layer of ITO (refractive index is 2.0) film to reduce the reflection of the whole structure and improve the overall absorptivity. The electromagnetic field in different wavebands, the influence of structure parameters on the overall absorptivity and the distribution of solar absorption characteristics are simulated. The results show that its high absorptivity band width (>90%) can reach 2,350 nm, which matches the solar radiation range on the earth (about 295–2,500 nm), and can perfectly meet the actual work requirements.

Materials and Methods
In the simulation process, we define the grating period as p and its width as t. The thickness from ITO layer to GaAs layer is defined as h1-h4. The thickness of W base is much larger than the penetration depth of light, so that the light transmittance T of the whole structure is approximately zero. The TM polarized plane wave is used as the light source to project vertically into the structure. The periodic boundary condition is set in the x direction and the perfectly matched layer is set in the z direction. The specific parameters of all materials are from the material library of FDTD solution software (Cao et al., 2014; Deng et al., 2015; Deng et al., 2018; Xu et al., 2021). The light absorption is still calculated by the formula A = 1-T-R, where T represents transmission rate and R represents reflection (Zhang et al., 2015; Long et al., 2016; Lv et al., 2018).
The simulation results are shown in Figure 2. In order to verify the rationality of our proposed five-layer structure, we also calculate the absorption without top layer ITO (shown by the red line in the figure) and the absorption with only three layers of Ti-GaAs-W (shown by the blue line in the figure). It can be seen from the figure that when there are only three layers of film structure, the overall absorptivity is very low, and the highest absorptivity in the whole band is less than 70%. For the case of adding GaAs grating without ITO film, the absorption rate has been greatly improved compared with the three-layer film structure, but the absorptivity is less than 90% in 1,030–1,410 nm and 2000–2,450 nm, which is still unsatisfactory. In our final five-layer structure, the absorption is more than 90% in the wavelength range of about 500–2,850 nm, which is up to 2,350 nm. Through calculation, the average absorption is 95% in the bandwidth of 2,350 nm, which meets the requirements of practical application perfectly.

Results and Discussion
First, we explore the influence of the main geometric parameters of the structure on the overall absorption, and the results are shown in Figure 3 Figure (a) shows the influence of the thickness of the top ITO film on the overall absorption. In the short wavelength range, the absorption changes greatly with the increase of the thickness, but at the long wavelength, it will gradually become better with the increase of the thickness and finally tend to remain unchanged. Considering the absorption of the whole band, we choose h1 = 80 nm as the optimal parameter. Figure (c) shows the effect of Ti film thickness on the structural absorptivity. When the thickness of Ti film is low, the absorptivity of the whole structure is poor, but with the increase of the thickness, it has a significant increase, and has a good absorption effect at h3 = 70–90 nm. The main reason is that the better impedance matching condition is met at this time. Figures (b) and (d) show the effects of the thickness of the two layers on the overall absorption. In figure (b), with the increase of h2, the long band absorption has been significantly improved. This is because the guided mode resonance of the grating layer is mainly related to its effective refractive index (Chen et al., 2013; Cai et al., 2014; Long et al., 2015), and the change of h2 will significantly change the effective refractive index of the waveguide layer. In figure (d), with the increase of the thickness, the absorption in the long band decreases gradually, while the absorption in the short band is almost unchanged. This is because the change of the film thickness will cause a weak change in the number of dielectric cavities.
FIGURE 3. (A–D) Absorption spectra corresponding to different geometric parameters.
Next, in order to more clearly and deeply explore the specific physical mechanism behind the broadband absorption phenomenon, we made a detailed analysis of its electromagnetic field distribution, and the results are shown in the Figure 4. The distribution of electric field and magnetic field at the wavelength of 500 nm, 1,500 nm and 2,500 nm of the incident light are plotted with the interval of 1,000 nm. The selected plane is xoz plane, and the top layer of ITO antireflection layer and GaAs grating layer are indicated with black dotted line. When the incident light wavelength is 500 nm, it can be seen from figures (a) and (d) that the electric field is mainly concentrated on both sides of the top structure and the interface with the air, and the magnetic field is distributed in the top two-layer structure, which indicates that in this case, the cavity film and GMRs mode are excited, and the joint effect of the two greatly enhances the overall absorptivity of the structure (Xu et al., 2020). Furthermore, it can be seen from figures (c) and (f) that the light penetrates further to the bottom layer and stronger SPPs are excited. From the corresponding electromagnetic fields of these three bands, we can draw the following conclusion: it is the coupling effect of GMRs, cavity film and SPPs that makes the broadband absorption possible.
FIGURE 4. (A-F) Electromagnetic field distribution of structures at incident wavelengths of 500 nm, 1,500 nm and 2,500 nm (xoz plane).
After the mechanism of broadband absorption of the proposed absorber has been proved, we have further analyzed its other photoelectric characteristics. Similar to the three-layer absorber mentioned above, we simulate the absorption spectrum when the incident angle is 0°–60° and the polarization angle changes from 0° to 90° as shown in the Figure 5. It can be seen from the figure that the designed absorbers have high absorptivity in the range of 0–60° and can withstand large incident angle changes, so the effect is very ideal; For the polarization angle, because the structure is not highly geometrically symmetric, the absorptivity inevitably decreases in the wavelength range of 1,000 nm–1500 nm, but it still maintains a high absorption in the whole wavelength range, and the effect is acceptable. In general, the absorption effect of the proposed absorber is much better than that of the previous absorber, which has better oblique incidence and polarization insensitive characteristics (Cheng et al., 2015; Callewaert et al., 2016; Vafapour, 2019).
FIGURE 5. (A) Absorption spectra at different oblique incidence angle. (B) Absorption spectra at different polarization angles.
Subsequently, as a solar absorber, the absorption capacity of the actual solar radiation is a very important index (Elshorbagy et al., 2017; Li et al., 2018; Nie et al., 2021; Xie et al., 2021). In order to explore its solar absorption in real situation, we selected AM1.5 spectrum to test its performance, and the results are shown in the Figure 6. In Figure 6A, the black line represents the solar spectrum at AM 1.5, and the red line represents the absorption of the proposed absorber under this solar radiation. It can be clearly seen that the red line and the black line coincide approximately in the whole 400–3000 nm band, which indicates that the efficiency of the absorber is very high and the absorption effect is very ideal. Figure 6B illustrates the previous conclusion more intuitively from the angle of how much energy is absorbed and lost. In the figure, the gray part represents the absorbed energy, and the red part represents the lost part. We can see that there is only a little energy loss in the short band, and it is insignificant compared with the area of the absorbed part. From these two aspects, it is easy to see that the proposed absorber has good practical effect.
FIGURE 6. (A) Solar energy absorption spectrum (B) Comparison of energy absorption and loss.
We also explore the ideal short-circuit current of the multilayer structure, and the results are shown in Figure 7. It can be seen that the short circuit current of the structure is high. When h2 = 200 nm, the short-circuit current is up to 684.851 A/m2. It can be predicted that the absorber will have a high photoelectric conversion efficiency, making the solar cell have more excellent performance (Mason et al., 2011; El-Gohary et al., 2014; Chen et al., 2019b).

Conclusion
In this paper, we propose a solar absorber composed of three-layer W-Ti-GaAs films and multi-layer metal semiconductor composite structure of GaAs grating. By adjusting the geometric parameters for many times, the broadband absorption at 500–2,850 nm, up to 2,350 nm, is realized, which greatly broadens the absorption bandwidth of the original simple structure. At the same time, the electromagnetic field distribution of the structure is given, which explains the reason of broadband absorption in physical essence. The spectrum, solar absorption and loss spectrum, ideal short circuit current and other parameters of oblique incidence and polarization angle change are studied, respectively. The results show that our solar absorber can meet the requirements of practical application. The proposed absorber provides theoretical basis for the design of perfect broadband solar absorber.
