Lasers are widely used in the field of new energy, mainly in the following aspects:

1. Photovoltaic solar energy

Laser cutting: Laser cutting technology is widely used in the photovoltaic solar energy industry for high-precision cutting of photovoltaic cells. Compared with traditional mechanical cutting, laser cutting has higher precision and efficiency, and can reduce edge damage during cutting and improve the quality of cells.

Laser marking: In the production process of photovoltaic modules, laser marking technology is used to print text marks in the module shell and soft glue, which can not only highlight the product brand, but also enhance the anti-counterfeiting of the product.

Laser welding: The application of laser welding technology in the photovoltaic solar energy industry is also becoming more and more extensive. Solderless welding technology has become the preferred technology for solar module file wiring. Laser welding not only improves power efficiency, but is also more environmentally friendly, saves materials, and increases the stability of wiring.

2. New energy vehicles

Laser welding: In the production of new energy vehicles, laser welding technology is widely used in the welding of automobile body-in-white, powertrain and lithium batteries. Laser welding, with its high efficiency and precision, greatly improves production efficiency while ensuring welding quality, which is of great significance to improving the safety performance and extending the service life of new energy vehicles.

LiDAR: As new energy vehicles develop towards intelligence, the penetration rate of LiDAR continues to increase. LiDAR combines multiple technologies such as optics, electronics, mechanics, software, and chips. It can help cars perceive the road environment and autonomously plan driving routes. It is an indispensable part of the intelligence of new energy vehicles.

3. Energy storage technology

In the field of energy storage, laser technology is also used in the production and recycling of batteries. For example, laser welding technology can achieve efficient connection of battery modules and improve the overall performance of the energy storage system. At the same time, in the battery recycling process, laser technology can be used to remove harmful substances in the battery and achieve environmentally friendly recycling.

4. Wind energy

Laser cutting: Laser cutting technology is used in the manufacturing process of wind turbine blades. It can achieve high-precision and low-cost cutting, improve the quality and performance of blades, and thus improve the efficiency of wind power generation.

Laser cleaning: Laser cleaning technology can be used for cleaning components in wind energy coating processes, such as cleaning sand, dust, coating residues on the surface of blades, etc., to improve the surface finish of wind turbine blades and provide high-quality surface conditions for coating.

5. Hydropower

In the field of hydropower, although laser technology is not as widely used as in the fields of photovoltaic and wind power, laser marking technology can be used in the production line of the cement industry to mark and print cement bags, realize the automatic management of the production line and track product quality.

In summary, the application of laser technology in the field of new energy covers photovoltaic solar energy, new energy vehicles, energy storage technology, wind energy and hydropower, etc., providing strong technical support for the development of the new energy industry. With the continuous advancement of technology and the continuous expansion of applications, the application prospects of laser technology in the field of new energy will be broader.
