Several organic acids have been investigated by other groups to control the surface of TiO2 in dye-sensitized solar cells. In terms of electron injection, organic acid as coadsorbents can induce even distribution of dyes on TiO2 surface and their binding mode, resulting in enhanced photocurrent. Here we present one way to probe the role of coadsorbent by precise control of adsorption process. Furthermore, we prepared coadsorbent with different alkyl chain length and compared device performance to see several factors to determine the adsorption process. |
