Cogenra today announced that its modules have broken two more world records, achieving unprecedented power levels using commercially available, unsorted photovoltaic (PV) solar cells and its propriety high-volume Dense Cell Interconnect (DCI) process.

  • 400W peak power achieved in a 72-cell format panel using DCI technology on commercially available mono-crystalline cells.

  • An unprecedented 352W achieved for multi-crystalline cells.

Washington Gas Energy Systems, Inc., a subsidiary of WGL (NYSE: WGL) today announced the completion of a one megawatt (MW) Cogenra Solar array that will produce renewable energy for Tucson Electric Power (TEP). The array at the Solar Zone, located at the University of Arizona’s UA Tech Park, consists of ground-mounted Cogenra T14 systems using Cogenra’s Dense Cell Interconnect (DCI) technology, which recently set three world records for peak power output. A ribbon cutting ceremony will be held to celebrate the completion of the solar array, the final project in the first phase of the UA Tech Park Solar Zone.

Cogenra Solar, a provider of high-performance solar technology, today announced that it has been awarded $2 million by the U.S. Department of Energy SunShot Initiative. With this award, Cogenra will scale its record-setting Dense Cell Interconnect (DCI) technology through an automated production line based in the United States.

Cogenra Solar, a provider of high-performance solar technology, today announced three world records using its Dense Cell Interconnect (DCI) technology. In a series of tests conducted by third-party laboratories, Cogenra’s DCI technology achieved up to a 15 percent increase in module power compared to currently available modules. This significant efficiency boost reduces both the module’s direct cost-per-watt and the total installed cost for solar power.

The record modules were constructed with commercially available, unsorted cells using Cogenra’s production-ready DCI manufacturing line. Independent verifications by DNV GL and TÜV SÜD of 60-cell format modules confirmed peak power outputs of:

  • 334W using N-type front contact mono crystalline cells.
  • 301W using P-type mono crystalline cells.
  • 288W using multi crystalline cells, higher than all commercially available multi or mono crystalline modules.

“Cogenra has developed an innovative product that achieves impressive efficiencies. DNV GL is thrilled to work with a domestic manufacturer that is pushing the boundaries of PV design and technology,” said DNL GV development engineer John Watts.

“It’s time to rewire the solar module,” said Cogenra Solar CEO and founder, Dr. Gilad Almogy. “Using available cell technologies, DCI delivers a booster shot of improved performance, reliability and cost reductions, leveraging nearly 60 GW of existing PV cell capacity. This much needed module-level innovation represents a significant breakthrough for solar technology and will accelerate solar adoption worldwide.”

Previous solar module technologies relied on ribbons, which shaded the silicon cells from sunlight, led to resistance losses and accelerated PV module degradation. Cogenra’s patent-pending DCI technology more efficiently connects cells on the module, eliminating the need for ribbons, solder-joints and inter-cell gaps. As a result, DCI modules achieve a range of benefits, including:

  • More power: 15 percent higher power that leads to reduced BOS and installation costs.
  • Superior reliability: Better withstands thermal cycling, hotspots, mechanical loads and external shading, reducing module degradation and leading to superior lifetime project returns.
  • Lower cost per watt: Improved efficiency reduces module cost-per-watt while leveraging existing cell lines.
  • Flexibility: Enables longer strings and shading resiliency.
  • Aesthetics: Eliminates ribbons and inter-cell gaps for a uniform all black appearance.

Cogenra is currently ramping up its U.S module manufacturing line, with DCI modules available for sampling and volume production starting in Q3 2015. Cogenra’s field proven DCI technology is currently in operation in a 1MW solar array at University of Arizona’s SolarZone.
