A SnO2 electrode is a promising candidate for a bottom electrode of dye-sensitized solar cells. One of the drawbacks is its low fill factor (FF). We clarified the cause of this low FF using our original hybrid cells consisting of carrier generation areas (a bottom layer consisting of TiO2/a dye layer) and carrier transport areas (a top layer consisting of SnO2 with and without a dye layer). A large decrease in FF was observed only when the SnO2 charge transport areas were covered by photo excited dyes, leading to the conclusion that back electron transfer reaction from SnO2 to oxidized dyes is a major route for the charge recombination. This was also confirmed by electron lifetime and dark current measurements.
