Water chiller technology is critical in the manufacturing of thin-film solar cells, with laser processes requiring high beam quality and precision. These processes include laser scribing for thin-film cells, opening and doping for crystalline silicon cells, and laser cutting and drilling. Perovskite photovoltaic technology is transitioning from basic research to pre-industrialization, with laser technology playing a vital role in achieving high-activity surface area modules and gas-phase deposition treatment for critical layers. TEYU S&A Chiller's advanced temperature control technology has been developed for use in precise laser cutting, including ultrafast laser chillers and UV laser chillers, and is poised to meet the growing demand for the laser equipment in the solar industry.
