JPSA Develops Laser Scribing Technique For Silicon Solar Cells


J.P. Sercel Associates Inc. (JPSA), a provider of laser scribing systems for solar cell processing applications, has developed a new proprietary technique for high-throughput edge isolation of silicon-wafer solar cells.

The laser scribing technique, called SuperScribe, produces narrow and precise cuts in silicon solar wafers, JPSA says. The company has achieved a variable width of 30µm and a depth of 16 µm with high-throughput isolation cuts at rates up to 300 mm per second with no recast. The solution also offers fully integrated debris control via JPSA's vortex debris control tool.

‘JPSA's most recent development allows us to offer our solar customers scribe speeds at 300 mm per second, and minimize debris due to proprietary beam delivery optics and optimized process control,’ comments Jeff Sercel, chairman and chief technology officer for JPSA.
