Professor Michael Graetzel of the École Polytechnique Fédérale de Lausanne (EPFL), Switzerland, announced in a paper in the journal Nature, a new two-step process for DSSC fabrication which raises the efficiency of these cells to 15%. Called dye-sensitised solar cells (DSSCs), reported efficiencies of 15% make them competitive with silicon photovoltaic cells.
