As shown in Figure 4(b), we could note that the variation trend of the electron lifetime measured by OCVD is the same as the EIS results.
We recorded the open circuit voltage decay (OCVD) of the solar cells with and without a surface treatment to investigate in-depth mechanism behind the efficiency improvement in using the colloidal treatment and annealing at 450[degrees]C.
Since there have been reports in the literature that the recombination kinetics between the Ti[O.sub.2] photoanode and the electrolyte might be dependent on the ionic liquid in the electrolyte [41, 42], we have performed OCVD measurements on solar cells with commercially available Solaronix electrolyte, without the intention of investigating how concentration, diffusion coefficient of the triiodide, or different cations affect the recombination, but rather just to confirm that the surface treatment is reducing the surface states of the Ti[O.sub.2] mesoporous film, and in doing so reducing the interfacial recombination regardless of the electrolyte.
According to Cameron and Peter [44], it is essential to also take into account the recombination with the electrolyte through the substrate when analyzing the OCVD curves.
