| dc.description | The adsorbed molecular species, such as H<sub>2</sub>O and I<sub>2</sub>, that produce electron acceptor states on the TiO<sub>2</sub> surface are found to generate 1/f noise in the electric current through nanocrystalline films of TiO<sub>2</sub>. It is suggested that the trapping and detrapping of electrons at the surface states is the cause of this noise. When the TiO<sub>2</sub> film surface is coated with dyes, the passivation of the active surface sites suppresses 1/f noise. Implications of 1/f noise on the functioning of the dye-sensitized solar cell, notably the effect of adsorbed iodine in inducing recombinations, are discussed. |
