Latest Patents

One of Weixu Long's latest patents is focused on a novel process for preparing passivated emitter rear contact (PERC) solar cells. This innovative process entails several key steps, including the removal of the damaged layer on the surface of silicon wafers while simultaneously polishing both surfaces. Additionally, it involves texturing, forming a PN junction, etching to remove glass impurities, and depositing a passivation film on the back surface. It also incorporates a passivating antireflective layer on the front surface, followed by creating local openings on the back surface, screen printing of metal paste on both surfaces, and sintering. Notably, the texturing step uses a catalytic metal etching approach to create a nanometer-level textured structure. By combining the surface layer removal and polishing into a single step, this invention simplifies the production process and significantly reduces production costs.
