    • This argument for the absence of a space charge layer assumes the nanoparticles are independent of each other. As pointed out in [Kronik et al., loc. cit.] a collective space charge can exist in a sufficiently thick nanoparticulate film, if it behaves as an ensemble. While this could be so for a completely dry system, the all-pervasive contact with the electrolyte, due to the mesoporous nature of the films, will effectively decouple the particles, via screening (cf. (D) in text) and make any such effect negligible when the film is immersed in a liquid.

    • Throughout this paper we give electron energies in electronvolts on the solid state scale, where electron energies are given as negative values measured from the vacuum level, which is taken as zero. To convert to the electrochemical scale, the sign has to be inverted and 4.5 eV subtracted (NHE ≈ -4.5 eV on the solid state scale).

    • The arguments given here are semiquantitative, with some of the limiting values deduced from measured photovoltages generated in the cell.

    • Kelvin probe experiments, using a recently developed method for measurements in liquids (Bastide et al., loc. cit.) are under way to measure this shift directly.

    • 2 is known to have a large density of surface electron traps. It is possible that the photovoltage is determined by the trapping levels, rather than by the bottom of the conduction band. Also, charge transport may occur via these surface traps. This point will be considered in more detail elsewhere.
