As a key technology in the green energy system, photovoltaic (PV) cells are accelerating toward low-carbon development under the global shift in energy structure. Driven by the “carbon neutrality” goals, solar cell technology continues to evolve, delivering higher efficiency and lower costs. From PERC to TOPCon, heterojunction (HJT), and XBC, a wide range of technical routes are advancing in parallel, creating a competitive yet dynamic landscape. As a result, the demand for precision gas control in each process is becoming more stringent. As a global leader in industrial and specialty gases, Messer has accumulated over a decade of experience in China’s photovoltaic industry and has become a trusted partner to many leading enterprises. We supply not only high-purity, highly stable gases essential for chip processing and cell manufacturing, but also provide on-site gas generation, liquid distribution, and localized service networks, ensuring smooth project ramp-up and efficient long-term operations.
