LayTec PearL - Monitoring Analyzes System Brochure

The PearL monitoring system analyzes the spectrum of photoluminescent radiation emitted from a probed surface after excitation with laser light. It is designed for in-line integration in production lines. Spectroscopic photoluminescence (sPL) gives access to information on the band gap, electronic defects and the related composition of materials, e.g. the gallium / (gallium+indium) ratio (Ga/(Ga+In) ratio) and copper (Cu) content of CIGS solar cells. LayTec’s sPL has a total measurement and analysis time of only 100 ms.
