Laser direct writing

by

A company, cutting-edge developer of equipment for solar panel processing, thin film solar cells, and commercial solar equipment announced the invention of Laser Direct Writing for tracking thin film solar panels. 

FUENTE – Global Solar Technology – 13/03/09

 Traditional methods to mark panels with tracking codes such as mechanical etching or engraving using a Co2 Laser can crack the surface of the glass thereby compromising the overall strength and quality of the glass. Due the harsh environments the panels must endure, these cracks can potentially lead to panel issues in the future. Additionally, the marks were not always clear enough to be scanned or read. 

 Laser Direct Writing is a non-destructive, patent pending laser marking technology which marks glass without damaging the surface while producing a readable image. This process does not require tapes or sprays to make the mark thereby eliminating any cleaning and post processing required with other methods. 

 “Panel manufacturers have been looking for a better way to mark panels with bar codes and UID marks,” said Maureen McHale, the Corporate Marketing and Public Relations Manager for the company. “Laser Direct Writing creates a black, semi-transparent or gold marking on glass and is ideal for tracking the life of the panel. This process does not damage the glass and ensures readability of the mark.”
