InnoLas’ laser scribers installed at Korean CIGS PV fab

InnoLas Systems GmbH says that it recently installed P1, P2 and P3 scribers at a 100MW copper indium gallium diselenide (CIGS) photovoltaic cell fabrication plant in Korea, showing that the firm’s laser technology for P2 scribing of thin-film solar cells is gaining global acceptance. So far this year InnoLas has delivered P2 laser scribers for structuring CIGS semiconductors to four different customers. The laser patterning tools support 250MW of production volume worldwide.

“The current installations are a further step in the successful roll-out of our laser scriber systems for thin-film solar cells,” says CEO Richard GrundmĂĽller. “Not only for the processing of CIGS but also for other semiconductors, e.g. CdTe [cadmium telluride] cells,” he adds. “Up to September this year we have already developed, built and installed P1, P2 and P3 scribing systems for a fab capacity of 300MW.”

InnoLas also offers laser systems for R&D applications. The firm has received an order for a multi-functional laser tool, tailored to the rigorous requirements in modern photovoltaic development labs. This system can process any individual pattern, either from the film side or from the glass side, with multiple wavelengths. All layers (P1, P2 and P3) can be laser scribed, and the processing side and process parameters are selected through simple menu commands. Mechanical scribing (P2, P3) is available on the same system. Features include integrated in-situ metrology, giving 100% control over scribe performance and enabling the user to optimize process parameters on the fly.

InnoLas is exhibiting its laser scribing systems at stand 3.0/G17b of the 27th European Photovoltaic Solar Energy Conference and Exhibition (EU PVSEC 2012) trade show in Frankfurt-am-Main, Germany (24-28 September).
