Introduction to the function of solar photovoltaic panel texturing equipment

What is the purpose of texturing a solar cell?

Texturing is used to reduce the reflection of light from the front surface and to improve light trapping in a solar cell. The first objective of texturing is to minimise the front-surface reflectance so that more photons remain, which can be absorbed by the solar cell resulting in a larger short-circuit current density, Jsc.

What type of surface texturing is used in photovoltaic?

Can Laser Surface texturing be used for solar panels?

Traditional coatings (TiO 2, SiO 2) are hazardous and not eco-friendly. Laser surface texturing has potential for producing self-cleaning solar panels. Optimizing laser parameters is crucial for super-hydrophobic glass surfaces. More research needed on laser parameter impact on glass for solar panels.

Do textured surfaces improve the performance of solar panels in harsh climates?

The textured surfaces exhibit improved anti-icing and self-cleaning by preventing water and ice adhesion, thus extending the operational lifespan of panels in harsh climates (Chakraborty et al., 2021).

Can laser textured surfaces be used for solar self-cleaning applications?

Several studies conducted for metals show the effectiveness of laser-textured surfaces in mitigating dust accumulation. The discussion also touches upon the challenges and advantages of laser-based texturing, due to cost-effectiveness, precision, and speed. Specifically addressing laser surface texturing for solar self-cleaning applications.

Where is the texturing process located in a solar cell?

In addition, the texturing process is located in the whole manufacturing process of the solar cell, highlighting the importance of the previous steps for a high-quality result. Chapter 3 provides a detailed introduction to advanced texturing with metal-assisted chemical etching in silicon solar wafers in general.
