Laser Marking of Solar Cells and Modules

Like any other first-class industrial product solar modules need to be marked and serialized to assure traceability of the manufacturing process. A perfect field of applications for high-speed and non-contact laser marking.

The options range from direct marking the aluminum frame over marking labels to direct marking of the glass substrates of thin film cells. High end suppliers of crystalline solar cells also provide a serialization of the individual cell. Depending on the marking method CO2 lasers or solid state lasers with second or third harmonic wavelength are used. The laser marking process takes less than 1 second per piece.

For this application we recommend the laser markers:
