“…At present, it is found that further optimization of the symmetry of silicon nanowires can achieve good extinction of natural light. Gao [16] and other researchers designed a silicon nanowire with a three-leaf top view, which increased the extinction capacity of a single nanowire by 85%. The principle of the design is shown in Figure 7.…”

In recent years, silicon nanowires have become a hot spot in the new material industry. As a kind of nanomaterial, silicon nanowires have excellent physical and chemical properties. However, the preparation method of silicon nanowires is not mature enough, which limits its further application. This paper mainly analyses the mechanism, advantages and disadvantages of several mainstream silicon nanowires preparation methods, and discusses the application of silicon nanowires and the future development direction. The results show that the chemical vapor deposition method can be used for large-scale preparation of silicon nanowires, while the laser ablation method can produce silicon nanowires with higher purity, and the electron beam lithography method has the advantages of high flexibility. However, the efficiency of these three methods is not high, and the cost is high, which is also the problem that the silicon nanowire preparation industry is looking forward to solve. Relying on the excellent conductivity, thermal conductivity and other characteristics of silicon nanowires, silicon nanowires can be applied to a variety of new energy industries. Based on the properties of silicon nanowires, this paper analyses the application of silicon nanowires in lithium batteries, solar cells, biosensors and thermoelectric materials in recent years, and forecasts its development trend, so as to provide a certain reference for researchers to further explore the research of silicon nanowires.

Photovoltaic devices are essentially solar energy collectors that convert incident photons into charge carriers. However, light reflection losses and external factors (e.g., fog) can lead to an inefficient utilization of incident photons. Therefore, the development of antifogging surface materials that can efficiently reduce reflection is a critical issue in the upgradation of photovoltaic devices. Herein, inspired by the wing scale structures of butterfly Trogonoptera brookiana, an antireflective and antifogging surface (BRFS) was prepared by a method combining biotemplate and sol−gel. Remarkably, the BRFS possesses a relatively large surface roughness and exhibits superhydrophilic property (static water contact angle of 0°), which can quickly split fog droplet film within 6.6 s to realize the antifogging effect. In addition, the final transmittance of BRFS is as high as 90.25%. Furthermore, as an application demonstration, BRFS was applied to the surface of the reverse organic solar cells. Without compromising the inherent performance of the panels, the BRFS enhances the electrical performance of the inverted solar panels by 18%. This work provides a simple and effective strategy for designing surfaces with superior antifogging and antireflective properties and offers significant potential value for the practical application of photoelectric devices.
