Abstract


  • Chemical surface treatment of porphyrin-sensitised titania films

    using bis-(4-methoxyphenyl)phosphinic acid after dye adsorption,

    results in large improvements in DSSC efficiencies which originate

    primarily from higher short circuit currents. The result was attributed

    to a positive shift in the TiO2 quasi-Fermi level with simultaneous

    retardation of charge recombination. High device

    performances have been achieved even using simplified electrolyte

    matrices devoid of the common additives, LiI and t-butylpyridine.
