(August 13, 2010) — DEK Solar is preparing to launch its Eclipse platform at this year’s EU PVSEC exhibition, being held in Valencia September 6-9. On stand B14 in Hall L2/H4, the DEK Solar team will introduce the advanced metallization line.
Senior Process Development Specialist, Tom Falcon, will also be presenting the company’s latest breakthroughs in Print-on-Print (PoP) technology during the show.
The Eclipse showcase on DEK Solar stand B14 will introduce the company’s high-throughput metallization solution for commercial solar cell production. The flexible platform design concept incorporates a series of field-retrofittable process modules that enable manufacturers to easily scale production to 1200, 2400 or 3600 WPH. The primary process modules, including the print head and loader, incorporate master controls and are designated as master units. Additional process modules operate as secondary “slaves.”
Eclipse performance can be easily upgraded in the field. Spacer process modules equipped with conveyors can be deployed at initial installation, then exchanged for additional print capacity; the line does not need to be reconfigured to accomodate extra modules.
In configurations of 2400 wph and above, Eclipse deploys multiple print heads that function independently in parallel, ensuring that if one head halts for operator attention, the others continue to print. Offering six-sigma repeatability for capability in advance of current solar cell requirements, the Eclipse platform also achieves print-on-print capability (PoP) – ±12.5µm at 2 Cpk.
DEK Solar Alternative Energy Business Manager, Darren Brown, explains: “In today’s competitive industry, solar manufacturers are targeting both enhanced cell efficiency and improved manufacturing productivity. However, as economic, industrial and political goalposts move around them, manufacturers are faced with the potential cost impact of what they need today not being necessarily what they will need tomorrow. Equipment cost-of-ownership is therefore critical. This is why Eclipse introduces the flexibility, configurability, modularity and field scalability necessary to achieve maximum value.”
Tom Falcon will be presenting DEK’s latest research print-on-print during the show’s conference program. Entitled ‘High Accuracy, High Aspect Ratio Metallization On Silicon Solar Cells Using A Print-On-Print Process,’ the new DEK Solar paper outlines how the development of an optimized PoP process can deliver measurable improvements in conductor aspect ratios, with dramatic efficiency gains proven to be sustainable in production volumes over many wafers.
DEK is a global provider of next-generation technologies and process support to solar cell manufacturers with solutions that include modular metallization platforms, precision screens and materials applications used in back side field coating, current-collector pattern and termination deposition for photovoltaic substrate production.
