New research has indicated that adding a layer of gold nanodots to the surface of indium tin oxide (ITO) could improve the efficiency of organic photovoltaics.
At present, the alignment between ITO and organic semiconductors limits the efficiency of solar cells. But a team at the University of Nantes, France, found that even coverage of 15% of the ITO recorded a notable difference in levels, providing a viable anode buffer for photovoltaic devices, reports Commodity Online.
The research, published in the Gold Bulletin journal, comes after another demonstration in efficiency improvements using gold, by the UK's University of Warwick, replacing the ITO electrode layer with a continuous, flexible and highly transparent ultra-thin gold film electrode.
