In the firing furnace the applied metal conducting tracks are first dried and then fired, to produce an electric contact on the front and rear sides of the solar cell. A new heating lamp technology, together with the belt guidance and cooling technology, ensures an optimum distribution of the temperature which provides excellent contact characteristics and thus an optimal filling factor.

Inline system for the front and rear contact characteristics of solar cells

• Max. heat-up rate of 80°C/sec
• Max. cool-down rate of 70°C/sec
• Pre-heated supply air covers entire surface
• Side lamps in the fired zone ensure homogenous temperature distribution
• Lighter feed transport belt reduces energy
• Quartz supports on the transport belt inside the furnace reduces shadowed areas
• Automatic belt tension
• Digital monitoring of supply and discharge air
• Sater and air cooling with heat exchanger
• Optional: after-burner
• Optional: stand-offs
