Platinum nanoparticle was electrodeposited on FTO conducting glass Substrate as counter electrode for application in dye-sensitized solar cells (DSSCs). Images of transmission electron microscope (TEM) and Scanning Electron Microscope (SEM) showed that platinum nanoparticle wits with the mean size of 20-30 nm and was homogeneously distributed on the surlace of the FTO conductive glass sheet. Using such a counter electrode, DSSC showed a 6.40% overall energy conversion efficiency Under one still illumination. It exhibited the same high-performance as the DSSC With a platinum counter electrode prepared by electroplating. Furthermore, the present preparation method for the platinum counter electrode has the advantage of low Platinum loading and transparence. (c) 2008 Published by Elsevier Ltd.
