  The solarzoom reporter was informed that on May 16, Manz, a high-tech industry integration solution provider, participated in the SNEC 2012 Sixth International Solar Energy Industry and Photovoltaic Engineering (Shanghai) Exhibition and Forum (Booth: E3 Hall, 310) and launched its The latest crystalline silicon solar cell wet process equipment: IPSG CEI 4800. The device is primarily used to remove highly doped layers on the back and edges of the wafer to create chemical edge isolation (CEI) and to remove the phosphorous-silicon glass (PSG) that was formed on the front side of the wafer during the previous diffusion process. "By benefiting from the new wet process equipment, we have actually more closely connected the photovoltaic process chain that Manz has built before. Integrating more processing steps into one unit will ultimately help customers reduce each watt. Manufacturing costs," said Manz CEO Dieter Manz.

As the name of the IPSG CEI 4800, its output can be as high as 4,800 pieces per hour. The newly developed sponge roller technology enables faster straight-through transport, which not only delivers wafers smoothly, but also ensures higher process stability. "With additional optimization, we can even increase production to 5,000 pieces per hour," said Kari Raudasoja, project manager for the Manz crystalline silicon division. In the trial run, even in the case of automated operation, the fragmentation rate of the new wet process equipment is not higher than 0.1%. The device is equipped with a magnetic coupling system that completely isolates gears, drives and chemicals. The new IPSG CEI 4800 is modular in design, easy to maintain and easy to interface with other modules or components. As a result, the product runs longer and costs more.
This device will be bundled with the Manz Speed ​​Picker for loading/unloading wafers. Yesterday, Manz's new factory in Suzhou held its opening ceremony, and IPSG CEI 4800 will also be officially put into operation at the plant. With over 20 years of experience in the wet process of printed circuit board (PCB) and flat panel display (FPD), and a new 16,000-square-meter facility, Manz will provide local customers with more efficient services. Price and quality products of German quality. It is reported that Manz will also launch new vacuum coating equipment and texturing equipment, and strive to become a supplier of full-process photovoltaic equipment.
