3W UV laser for precise cutting of solar panels

Electricity and solar energy are the future of energy. At present, the use of solar energy is still in its infancy. The cost of making solar panels remains high. The production of a solar panel requires extremely high cutting accuracy, and RFH lasers can do it.

The mainstream solar panels are now divided into monocrystalline silicon and polycrystalline silicon. No matter which type, the main material of solar panels will eventually be "silicon". The principle of power generation is to convert solar radiant energy into electrical energy by absorbing sunlight, thereby charging thin-film solar cells.

To make a solar charging board, the first process is slicing, which requires cutting a whole piece of silicon rod into small pieces. This process requires extremely high cutting technology. If there are burrs or residues on the edge, the silicon wafer will be wasted. Therefore, the heat-affected area needs to be reduced during cutting, and the silicon wafer cannot be bent due to heat, so it needs to be heated quickly, by rapid cooling.

Compared with traditional mechanical cutting methods, laser cutting of silicon wafers can minimize the impact of cutting, and the processing accuracy is higher, and the use of lasers does not require replacement of consumables, which saves costs in disguise.

In the cutting of solar panels, RFH S9 series lasers have an industry-leading advantage.

1. The best laser wavelength for cutting solar panels is about 355nm. The laser wavelength of RFH S9 ultraviolet laser is 354.7nm. According to the actual needs of users, 3W~10W powers are available to meet the needs of different scenarios.

2. With RFH's unique control technology, the RFH S9 series can be adapted to different application scenarios. The fully digital power control technology reduces the cost of learning, is easy to learn, and is convenient for monitoring.

3. The RFH S9 series is smaller in size, saving space, customers do not need to make a large optical path, the installation is lighter, and the cost performance is extremely high.

Fighting the future, RFH laser

Today's solar panels are basically fixed on the material, and the variable is the coating. The solar energy absorption rate of solar panels is about 70%, but the latest solar panel coating can achieve the absorption rate of more than 95%, which can make better use of energy. From the perspective of future energy, solar energy is a greener and more environmentally friendly energy source than electric energy, which is to fight for the future in energy utilization.

In addition to laser cutting, the RFH S9 series has excellent performance in 3C, clothing, glassware and PCB cutting and other fields, whether it is marking or engraving can be excellent enough. The stable cavity structure and strong expansibility of the S9 series also play a role in many fields. Compared with the same type of products, the RFH S9 greatly saves user costs.

RFH has been deeply involved in the field of industrial-grade high-end solid-state lasers for many years, using leading technology and sufficient industry experience as a backing, product quality control is very strict, and the high standard of dust-free production makes RFH's product life far better than industry standards.
