During the ACS session on solar energy I kept hearing references to the Graetzel Cell — apparently high efficiency but short life. For you researchers, try this link for a start:
Michael Graetzel, the father of the Graetzel Cell, a kind of dye-sensitized solar cell, has developed an improved photoelectrochemical cell that will more efficiently and cost-effectively produce hydrogen. Details of the unprecedented development are expected to be released by the Journal of the American Chemical Society within the next 10 days.
Michael Graetzel first developed the Graetzel Cell in 1991, which uses low-cost materials and simple apparatus in manufacturing. The cells have a simple structure and the newest breakthrough technology is supposed to increase quantum efficiency from the current level of 37-percent to an all-time high of 42-percent.
