DSSCs are composed of dye molecules, nanocrystalline titanium dioxide, and electrolytes containing a redox couple and counter electrode. The oxidized dye is then regenerated by electron donation from an electrolyte solution, which normally contains the iodide (I-)/triiodide (I3-) couple. This catalyst is needed to reduce the voltage loss due to charge-transfer over potential at the counter electrode. A counter electrode with high electro-chemical activity is a very important factor in achieving a high DSSC Photoconversion efficiency, maintaining a large application area. |
