“…Consequently, it is impossible to obtain texturization of homogeneous structure on the whole surface [6][7][8][9]11]. Another possibility is mechanical texturization [14]. Unfortunately, it is also not satisfactory due to possible mechanical damages, resulting in breakability and fragility of silicon and * Corresponding author.…”

“…At present, chemical corrosion is commonly used in the industry to prepare upright random pyramid textures for monocrystalline silicon solar cells . In addition, mechanical texturing technology, laser texturing, reactive ion etching (RIE), and other surface texturing technologies can also be used to prepare effective light‐trapping structures. The reflectance of the photovoltaic crystal silicon surface can be effectively reduced by mechanical texturing technology, but this method may cause mechanical damage to the silicon surface.…”

Herein, the purpose is to study the antireflection performance of the silicon surface with a V‐ring groove texture. Based on the principle of geometrical optics, a numerical model of 3D ray tracing is established to calculate the weighted reflectance of the textured silicon surface with V‐ring groove structures, and the calculated results are in good agreement with the measured reflectance results by a mechanical processing experiment. Then, the reflectance of the V‐ring groove textured silicon surface with different parameters is simulated and analyzed through the established model, and better parameters of the V‐ring groove structure for antireflection are determined by considering actual processing conditions. Finally, the weighted reflectance and reflectance spectra of the V‐ring groove textured silicon surface with better parameters are calculated. It is found that the lowest weighted reflectance of the silicon surface with improved V‐ring groove texture is 5.53%, and the lowest weighted reflectance is reduced by about 5%, compared with the chemically etched pyramid texture of which the weighted reflectance is 10.54%. In addition, when the incident angle is less than 50°, the weighted reflectance of the silicon surface with an improved V‐ring groove texture remains less than 10%.

“…In fact, one of the most important factors influencing solar cells performance is the reflectivity of its front side [6]. Conventional texturization of silicon usually involves chemical and electrochemical methods [7] or mechanical methods [8]. However, there is a real need for processes capable of producing layers of regular texture.…”

The application of laser beam welding to aluminum alloys has some complications, mainly due to their high reflectivity, high thermal conductivity and low viscosity. In order to increase the laser absorption of aluminum alloys, some surface treatments has been applied in the literature, such as the application of dark coatings or sandblasting. However, these conventional superficial treatments have some drawbacks, such as the low weld penetration, the possibility to undergo magnesium evaporation and the impossibility to control and/or change the superficial properties of the treated samples. In the present contribution, laser texturization treatments have been performed with a fibber laser for the first time on aluminum alloys to increase their weldability. These textured samples have shown better weldability than reference sandblasted samples.
