LayTec Debuts PearL Metrology System For PV Applications

Germany-based LayTec has introduced PearL, an in-line metrology system for solar applications. The optical system measures photoluminescence spectra of thin-film modules in production lines.

The system is designed for measuring in copper-indium gallium diselenide (CIGS)-based production lines. Photoluminescence spectra allow fast detection of the effective gallium content of the absorber during the production process, LayTec says. A product option for cadmium telluride absorbers is also available.

PearL features LayTec's laser-simulated spectral photoluminescence technology for PV absorber layer characterization and process control. The technology is designed to deliver rapid quantitative material parameters based on spectroscopic responses, the company says.
