Heraeus Photovoltaics, a technology solution provider for the renewable energy industry, formed a joint manufacturing and sales partnership with Ulbrich Solar Technologies t0 manufacture and market the new Heraeus line of patented advanced Selectively Coated Ribbons (SCR) for module manufacturing customers.
PV ribbons play an important role in the manufacture of solar cell modules, interconnecting the cells together to a string that is placed inside the module. While traditional PV ribbons typically have a solder coating on them, the Heraeus SCR is a tabbing ribbon designed with stripes of highly-reflective white coating running across its edges, with the solder coating in the middle. As a result, the new design delivers significant improvements in functionality and performance, namely:
- A power gain of up to 2.2 watts on module level;
- All relevant soldering technologies tested and compatibility with different stringers proven;
- Reliability tests have been successfully completed: TCT 400 passed and 240 kWh/m² UV-DH passed;
- Versatility to work on conventional module designs as well as modules made with half-cut cells and bifacial modules.
This first of its kind coated ribbons deliver increased power while providing solar module manufacturers a “plug and play” solution that easily integrates into their existing manufacturing process without requiring any additional equipment.
Peter Berghofer, the General Manager of Ulbrich of Austria GmbH, said, “New products for module manufacturing need to meet demanding requirements and must be cost competitive, innovative and reliable. The new SCR fulfils those expectations by increasing the power of every single module without any investment or additional effort for the module manufacturers. We expect this product to be a real game changer in module manufacturing.”
