Abstract
- Abstract: The photovoltaic properties of nanoporous TiO2 film treated with Al3+ ions have been investigated by the spectral and transient photovoltage (PV) technique. The performances of the dye-sensitized solar cells (DSSCs) with different amounts of aluminum oxide were compared. The results showed that with increased amount of aluminum oxide, the spectral PV responses blue shift (with the exception of the 0.1wt%) and the time of the transient PV maximum increase. The performances of the corresponding cells were improved. These results indicated the dependence of the DSSCs performances on the charge dynamics in the corresponding nanoporous TiO2 film.
