A team led by the inventor of the Grätzel solar cell describes a new deposition process for manufacturing cells photosensitive pigment having reached laboratory a yield of 15%.

Photosensitive pigment cells, invented in 1991 by Professor Grätzel, see their performance to reach or exceed that of traditional cells without sacrificing stability, said the EPFL in a statement.

“Our research on solar cells photosensitive pigment leads – laboratory – in excess of 15% yields and our cells have been validated with a world record 14.1%. With this level of efficiency, DSSCs technology (dye-sensitized solar cells) is extremely competitive with conventional solar cells, especially if one considers that the DSSC does not need ideal sunshine conditions for producing energy. In the task that is to pass this technology from the stage of laboratory to the industrial one, we are particularly attentive to the Dyesol program to enable commercial deployment within the shortest possible time,” said Professor Grätzel.

One of the many advantages of DSSCs technology compared to conventional silicon solar cells is that energy can be generated even in low light conditions (dawn, dusk, cloudy conditions, artificial lights, shaded or indirect).

To get this record performance for this type of technology, solar cells have benefited both the innovative technology and key materials such as pulp developed by Dyesol: 18NR-T Titania. “Recent advances in the technology of dye solar cells are really amazing. This is the dawn of a new era in the production of an effective and affordable renewable energy,” said the Dyesol President Richard Caldwell.
