　　Dye-sensitized solar cell （DSSC）. photoelectrochemical device consisting of a dye-sensitized anode, a redox electrolyte, and a counter electrode, has attracted grow ing interests because of its merits on low-cost, relatively high power conversion efficiency, easy fabrication, and environmentally friendly. The photoanode of DSSC can be seen as a’vehicle’to transport the electrons injected from the excited dye molecule to an external circuit. Therefore, it can significantly affect photocurrent and...
