Over the past few years, the solar panel manufacturing industry, and in particular, the thin film technology, has grown at a tremendous rate.

scribing laser for solar panels

Recent breakthroughs in the manufacturing technology has reduced costs making this technology competitive with the other energy sources.

The new thin film panel manufacturing process involves laser scribing techniques to make the panels.

A typical laser used in this process may have the following specifications:
Specifications Value
Wavelength 532nm
Pulse width 10 - 35ns
Power range ~1W
Repetition rate 20 - 100kHz
Beam size <1mm dia.
Profile Gaussian
ultra 19K laser power meter

The scribing process can have high average power and peak power densities, and so is suited to the W5 absorber as used in the Ultra 19K W5 laser power detector.

This surface absorber can withstand up to 100 kW/cm2 average power density, which is the best average power density and damage threshold available in the industry.

The Ultra is also available with various cooling options depending on the power of the laser, including:

  • 15W stand alone
  • 30W heatsink option
  • 50W heatsink option
  • 50W air-cooled option
  • 50W water cooled option

Furthermore, the solar panel business requires the use of solar simulators to test the solar cells.

The XLP12 is the perfect tool to measure the low irradiance levels of these sources. The optional fused silica filter also helps to isolate the detector from IR interference.
