JPSA Intros Thin Film Photovoltaic Laser Scribing Machines
Manchester, NH — J P Sercel Associates (JPSA) has introduced a family of industrial laser scribing systems to meet the manufacturing requirements of thin-film-on-glass solar panel alternatives.

Built on the successful ChromaDice DPSS laser platform, the new PV Series are Class 1 enclosed laser scribing systems for isolation and series interconnection of thin film solar cells. JPSA uses high peak power, short pulsed Diode Pumped Solid State (DPSS) laser sources to rapidly, selectively and accurately remove a wide range of thin films from large glass, metal or polymer substrates. A variety of wavelengths suitable for different layer materials are available including 1064nm, 532nm, 355nm and 266nm.

These systems use advanced laser technology scribing to rapidly and accurately produce fine scribed lines with >30MΩ isolation. The range of applications includes: P1 Front Contact: Transparent Conducting Oxides (TCO) such as ITO, IZO, SnO2, and ZnO2 can be scribed using 1064nm; P2 Semiconductor: (a-Si,) Cadmium Telluride (CdTe,) and Copper Indium (gallium) diselenide (CIS or CIGS.) can be scribed using 532nm or 1064nm; P3 Back Contacts: Metals such as Al, Mo or Au can be scribed using 532nm or 1064nm; Border deletion: Bulk deletion of all three layers to provide an edge isolation border may be achieved using high power 1064nm lasers.

The PV Series workstations are modular and scalable to accommodate glass sheet sizes currently up to 1300 x 1300mm. Panel throughput or Takt time on a single tool can be matched to the overall production requirement by adding more laser power.
