DEK Solar showcases its latest breakthrough photovoltaic metallization solutions at the PVSEC show in Hamburg. Highlights will include the recently launched PV3000 high throughput metallization platform, along with its pioneering print-on-print capabilities. DEK’s PV3000 screen printing platform is a very high throughput complete metallization solution. Deploying multiple print heads operating in parallel, the display will show visitors in live demonstrations how, if one head halts for operator attention, the others will continue to print – virtually eliminating downtime. Delivering six-sigma repeatability for capability in advance of current solar cell requirements, the platform’s inherent accuracy and repeatability is ideal for demanding technologies such as selective emitter and progressive techniques such as print-on-print. Indeed, with these processes fast-becoming industry standard, the PV3000 achieves print-on-print capability (PoP) – +/- 12.5 microns at 2 Cpk. Visitors to Stand B5/73 will also be able to find out more about the company’s ability to provide solutions for print-on-print to substantially extend productivity and end-of-line yield. Ideal for solar manufacturers looking to enhance cell efficiency and drive down cost-per-watt, print-on-print is designed to give finer grid lines more height, printing the lines twice over to enhance current-carrying capacity without shadowing underlying silicon substrate.
