... introduction or removal of incident light. The presence of transient photoconductivity is well documented in nanocrystalline TiO 2 thin films [24, 25, 33], but is interesting to observe in a single ... of incident light intensity. Before dye attachment, the current increases linearly with the light intensity, which indicates the carriers excited in TiO 2 is proportional to the number...
