Specialty light sources from UV to infrared for the efficient production of solar cells

Infrared emitters and Xenon flash lamps for solar modules

Solar modules convert sunlight into electric energy. They shall generate as much solar power as possible without wasting energy during production or on the roof. Specialty light sources help produce solar cells efficiently and test them for optimal function during operation.

Infrared emitters for drying and sintering

Drying, sintering or string soldering – production of solar cells requires heat in many process steps. Infrared radiation transmits energy without contact and with high energy. This saves time and production space.

The advantages of infrared heat can be used even under extreme process conditions. The QRC® nano reflector substantially improves the performance of heat processes in a vacuum or at high ambient temperatures.

See a QRC® emitter at work in our  Video .

Your advantages with infrared radiation:

  • Infrared radiation is transferred without contact and hence optimally suited for heat processes in a vacuum
  • Infrared emitters react quickly and are therefore easy to control and regulate
  • Infrared radiation provides high power for modern manufacturing methods

Xenon flash lamps for sun simulation

Solar cells and solar modules need to be tested to check production quality and to characterise the cells and assign them to power classes. Only cells that are optimally compatible with each other are combined to form a module. This requires reliable and reproducible light sources which have a spectrum that comes as close as possible to that of the sun. Xenon flash lamps, small and ring-shaped or linear and up to two metres long, are suitable light sources.

Your advantages when using xenon lamps for sun simulation:

  • Standard sunlight simulation from UV to IR
  • Stable and repeatable output, from pulse to pulse
  • Uniform output distribution
