Notes:
The current–voltage characteristics of dye-sensitized porous-TiO2(por-TiO2) solar cells are investigated in the dark and under illumination at light intensities up to 1500 W/m2 and temperatures between −5 and 80 °C. In the dark, the barrier height and the ideality factor of the por-TiO2/electrolyte contact are 0.67 eV and 1.05, respectively. The very low effective Richardson constant indicates the importance of diffusion for transport. A current-dependent effective barrier height has been established under illumination of dye-sensitized por-TiO2 solar cells. The barrier lowering effect should be caused by the low neutralization rate of the positively charged dye radicals in the electrolyte. © 1998 American Institute of Physics.
