A Solid-State Dye-Sensitized Solar Cell Fabricated with Pressure-Treated P25−TiO2 and CuSCN: Analysis of Pore Filling and IV Characteristics
Abstract
Solid-state dye-sensitized photovoltaic cells have been fabricated with TiO 2 as the electron conductor and CuSCN as the hole conductor. The cells show photocurrents of ≈8 mA/cm 2, voltages of ∼600 mV, and energy efficiencies of ≈2% at 1 sun. The CuSCN was deposited into the pores of the nanoparticulate TiO 2 /dye film from dilute solution in propylsulfide. The degree of pore filling achieved is near 100% for TiO 2 films <2-μm thick and falls to ≈65% for films near 6 μm. The final drying step after the CuSCN deposition is shown to be critical; drying in vacuum or argon is required for photocurrents above 2 mA/cm 2 . The photocurrent IVs of these cells are fit to a single diode equation and the results are discussed and compared to those for equivalent photoelectrochemical cells, and similar solid cells composed of ZnO/dye/CuSCN.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
