VC funded ‘low cost’ CPV technology developer, Cogenra Solar has claimed to have set three performance records for conventional 60-cell format n-type, p-type and multi crystalline modules.
The performance records were said to have been achieved by using its Dense Cell Interconnect (DCI) technology, originally designed for its low-cost CPV technology but further developed for connect conventional cell/modules, which is claimed to eliminate electrical losses from cell to cell as per tabbing and stringing.
Cogenra Solar said that it used commercially available, unsorted cells with modules assembled with the DCI technology at its production manufacturing line, which were then flash tested for independentverification by DNV GL and TÜV SÜD.
The DCI technology enabled a 60-cell N-type mono front contact module to generate 334W. A 60-cell P-type mono module was said to generate 301W, while a 60-cell P-type multicrystalline cell was said to generate 288W.
The company did not say what the original commercially available cell types were expected to generate, though claimed at least a 15% improvement across the cell types when each module was flash tested.
“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 60GW of existing PV cell capacity. This much needed module-level innovation represents a significant breakthrough for solar technology and will accelerate solar adoption worldwide.”
The company also claims that the DCI technology better withstands thermal cycling, hotspots, mechanical loads and external shading, reducing module degradation and leading to superior lifetime, while reducing module cost-per-watt while leveraging existing cell manufacturing lines.
Cogenra Solar said that it was ramping up its US module manufacturing line in Silicon Valley, with DCI modules available for sampling and volume production starting in Q3 2015.
