Notes:
We present intensity-modulated photocurrent and infrared transmittance measurements on dye-sensitized solar cells based on a mesoporous titania (TiO2) matrix immersed in an iodine-based electrolyte. Under short-circuit conditions, we show that an elementary analysis accurately relates the two measurements. Under open-circuit conditions, infrared transmittance, and photovoltage measurements yield information on the characteristic depth at which electrons recombine with ions (the "locus of recombination"). For one particular series of samples recombination occurred near the substrate supporting the titania film, as opposed to homogeneously throughout the film. © 2002 American Institute of Physics.
