The printed front &rear contacts are fired into the PN junction layer to form an ohmic contact through firing process, which allows the electrical energy collected by the fingers to flow out through the busbars.
Drying→ Pre-firing→ Firing→ Cooling
Operating power reduced by more than 50%.
Based on the existing process and production capacity, the total length of the firing furnace is shortened by nearly 40% compared with the traditional inline firing furnace.
With high-purity quartz roller conveyor, no metal material and no compound formation.
Without metal mesh belt circulating in and out of the furnace for heat exchange, which ensures better process stability.
Adopt Siemens PLC and industrial control system, with mature electric control technology and stable performance.
