IMPALA Photovoltaic: Processing of thin-film solar modules

The IMPALA laser system was designed for the photovoltaic industry as a work station to provide precise and reliable laser processing over a large area. It offers state-of-the-art technology for laser processing thin-film solar modules. Typical processing steps for thin-film technology are:

• Laser scribing / laser isolation for series interconnection of thin-film modules.
• Removal of material around the panel edge to isolate the panel against the panel frame (edge deletion).
• Laser scribing of thin-film layers P1 (laser), P2 and P3 (mechanical).

The large X/Y cross table can be sized to meet customers’ specific requirements. Handling and alignment of the substrates are fully automated with micro-meter accuracy over the entire panel area. Depending on the machine configuration, the thin-film panel can be processed with multiple laser beams in parallel.

The InnoLas IMPALA system is designed as a work station for precise processing over a large area with state-of-the-art technology for CIS respectively CIGS and other thin-film modules like amorphous silicon (a-Si:H), cadmium telluride (CdTe) or microcrystalline silicon.
