Electronic transport in dye-sensitized nanoporous TiO2 solar cells-comparison of electrolyte and solid-state devices
Article Abstract:
A comparison is made on the electronic transport properties of dye-sensitized solar cells using a liquid electrolyte with those of one using an organic hole conductor. It is found that 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.

Influence of the built-in voltage on the fill factor of dye-sensitized solar cells
Article Abstract:
Experiments with variations of the front contact material to the TiO2 network of dye-sensitized solar cells (DSSC) show that the resulting variations of the built-in voltage have no effect on the open circuit voltage V (sub OC) of those devices. V (sub OC) is determined by the steady state between photocarrier generation and recombination in the TiO2/dye/electrolyte system.

Reply to Comments on "electronic transport in dye-sensitized nanoporous TiO2 solar cells-comparison of electrolyte and solid-state devices". On the photovoltaic action in pn-junction and dye-sensitized solar cells
Article Abstract:
The comments of Gregg, Bisquert, and Augustynski on the interpretation of the exponential increase of the device capacitance with increasing negative voltage bias in terms of a diffusion capacitance like that encountered in pn-junction diodes is challenged. It is proposed that a common outlook would bring progress in a better understanding of the subject.
