Day4 Energy claims 18% cell efficiencies for multi-crystalline cells

Day4 Energy, Inc. has said that its Generation II solar cell technology and processes have reached a new performance milestone with conversion efficiencies reaching 19 percent on mono-crystalline and 18 percent on multi-crystalline silicon materials in its R&D lab. Importantly, the company claims that when the Gen II technology is put into production over the next 18 months, production costs will have been reduced by up to 25 percent compared to conventional production costs.

“Our first generation 14.7 percent efficiency Day4 MC module, which has been in commercial production since 2006, already places us among the industry’s highest performing multi-crystalline products,” said Professor Leonid Rubin, Chief Technology Officer of Day4 Energy. “With the second generation of our proprietary solar cell designs we are taking a major step towards making solar energy cost competitive with conventional sources of electrical power generation.”
