Dye solar cell (DSC) developer, Dyesol has claimed a breakthrough in solid-state DSC efficiency of 11.3%. Typically best-in class efficiencies for such cells have been in the 5% range.
According to the company, the breakthrough was made by shifting from liquid-based to solid-state deposition systems. The work was said to have been carried out by Dysol scientist, Dr. Peng Qin, based at the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland. However, the company did not make it clear whether EPFL verified the results.
Richard Caldwell, chairman of Dysol said: “The business case for solar remains compelling, however there is every reason to question which technologies will emerge from the current solar industry maelstrom as winners. Today's announcement represents a quantum leap for Dyesol and its commercialisation partners and we look forward to a rapid transition from the laboratory to the production line.”
The company had noted in its March quarterly report that a previous deadline for an announcement on commercialisation arrangements with Tata had been postponed from May 31 to July 31. The company also noted that it hoped to announce significant updates with other commercial partners, Pilkington and Timo in the second quarter of this year.
