• Solar Cell Provider, Ever Energy Co. Ltd, Signs Agreement to Manufacture High Efficiency Solar PV Cells With Day4 Energy’s stay-powerful™ Technology

Day4 Energy Inc., a leading global provider of solar photovoltaic (PV) products and solutions has signed an agreement with Ever Energy Co. Ltd, a top producer of high efficiency solar PV cells in Taiwan, to manufacture Day4 DNA™ cells with Day4 stay-powerful™ Technology.

With a focus on high end products in terms of both quality and efficiency, Ever Energy and its experienced research and development division will apply the innovative blueprint and efficiency boosting benefits of stay-powerful™ Technology as a platform to launch new cell designs in the coming months.

“By implementing Day4 Energy’s state-of-the-art cell manufacturing processes and stay-powerful™ Technology, we can provide a differentiated product and significant competitive edge for module manufacturers wanting to produce a truly differentiated product”, commented Dr. J.J. Lee, president of Ever Energy. “Our next generation solar cells will maximize customer value, offering high quality technology over traditional solar PV cells for our customers to stand out in an increasingly competitive market.”

Stay-powerful™ Technology, the core innovation behind Day4 DNA™, is a process that revolutionizes the collection of power solar electric cells generate and how they are interconnected within a module. It is a direct replacement of the conventional, high temperature solar cell soldering process.

“We are proud to partner with Ever Energy.  Together we can offer module manufacturers around the world a clear path to producing higher value, lower cost products for their customers”, noted George Rubin, president of Day4 Energy. “Without the need for high temperature soldering, electroluminescence or concern for micro-cracks, cell producers can offer module manufacturers the added benefits of extremely low cell to modules (CTM) power losses. No other cell technology does all of this”, concluded Mr. Rubin.
