The inkjet printing technology for solar cell insulating adhesive adopts a non-contact inkjet process to precisely deposit insulating adhesive layers. It achieves effective insulation between fine grid electrodes and main grid electrodes, eliminating short-circuit risks. Nano-scale droplet control optimizes coating uniformity, which fits low-temperature processes such as HJT and reduces material waste while improving yield rate. Compatible with flexible substrates, this technology facilitates mass production and reliability improvement of high-efficiency back-contact cells.
