LionTec Precision Inkjet & Functional Printing Solution for PV

LION TEC PV coding system resolves three critical pain points including high-temperature tolerance, PID resistance and wafer microcrack prevention, enabling full-chain traceability and functional printing for silicon wafers, PV modules and perovskite products.

Adopting non-contact inkjet printing avoids physical damage to silicon wafers; direct functional coating printing replaces outdated traditional crafts with zero material waste, upgraded printing precision and ultra-low power consumption. Our technology has obtained official certification from multiple leading PV manufacturers worldwide.

Three Core Marking Challenges in PV Manufacturing

  • Strict Compliance for Traceability: IEC TS 62994 mandates closed-loop full-process data tracking spanning silicon wafer, solar cell and finished PV module.
  • Extreme Environmental Durability: Solar cells undergo high-temperature processing up to 200℃ during PECVD coating; finished modules require 25-year outdoor resistance against PID degradation under damp-heat and UV exposure.
  • Process Upgrade Demand: Conventional screen printing and adhesive labeling restrict yield improvement.
