Abstract:

The influences of ZnO photoanode structure on the properties of ZnO dye-sensitized solar cell were studied in this paper. Four kinds of ZnO photoanode films prepared from ZnO nanopowders, nanorods, nanosheets and aggregates were investigated. Their photovoltaic parameters were discussed and compared. ZnO cell consisted of ZnO aggregates had optimal properties, photoelectric conversion efficiency, open circuit voltage, short-circuit current and the fill factor of ZnO aggregates cells were 2.15%, 0.64V, 6.47mA•cm-2 and 0.52, respectively.
