Electronic Transport in Dye-Sensitized Nanoporous TiO2 Solar CellsComparison of Electrolyte and Solid-State Devices

This article compares the electronic transport properties of dye-sensitized solar cells using a liquid electrolyte with those of one using an organic hole conductor. Both types of solar cells differ by the reference energies for recombination and, in particular, by their recombination probabilities of photoinjected electrons from the titanium dioxide into the respective contact medium. For voltage…
