Dyesol predicts its record-breaking dye-sensitized solar cell will usher in a new era.

Michael Grätzel, a professor at the Swiss Federal Institute of Technology (ETH), Lausanne, claims to have developed a solid-state dye solar cell (DSC) with an efficiency for converting sunlight to electricity that exceeds 15%, a world record, he says.To create the cell, Grätzel used a new DSC paste featuring materials made by Australia’s Dyesol. Grätzel, who is chairman of Dyesol’s technology advisory board, says DSCs can now be competitive with conventional solar cells.
