Globalcean Releases Seed Laser Series for Photovoltaic Industry

As the global demand for renewable energy continues to rise, photovoltaic (PV) technology, distinguished by its clean, efficient, and sustainable attributes, is progressively emerging as a leading direction in the global energy transition.

In recent years, China's photovoltaic cell industry has witnessed continuous market expansion, indicating promising prospects for the industry.

Laser technology assumes a pivotal role in the production processes of PV cells, including laser scribing for thin-film cells, film opening for crystalline silicon solar cells, laser doping, laser cutting, laser drilling, and laser edge engraving. According to data, the total market volume for PV laser equipment is 2.246 billion RMB in 2022 and 4.339 billion RMB in 2023, with year-on-year growth rates of 34% in 2022 and 93% in 2023. With the scaling up of production capacity for N-type photovoltaic cells and the continuous iteration of new technologies, the demand for photovoltaic laser equipment is expected to continue growing.

The seed laser, as the core component of the laser, is a crucial factor determining the output parameters, stability, reliability, and lifespan of the laser. For instance, in the case of a picosecond seed laser, the output center wavelength and pulse width directly determine the laser’s output center wavelength and pulse width. Similarly, for a femtosecond seed laser, the compressible pulse width dictates the minimum pulse width of the femtosecond laser. The power stability and pulse width stability of the seed laser establish the upper limits for the laser's power stability and pulse width stability.

During the processing, the seed laser often achieves various processing requirements by altering the laser's frequency, power, wavelength, pulse width, and polarization state. This enables the optimization of the photovoltaic cell’s photoelectric conversion efficiency, cost reduction, and promotes its application in the field of renewable energy.

With the development of the photovoltaic industry and the increasing market demand, the application of seed laser in the photovoltaic industry has become more widespread and critical. In recent years, Globalceanhas actively dedicated itself to research and development, catering to diverse application needs and product categories within the photovoltaic industry. Globalcean has successfully developed seed laser series tailored to the evolving demands of the photovoltaic industry, which includes picosecond passive mode-locked seed laser, femtosecond passive mode-locked seed laser, and semiconductor pulse seed laser.
