Efficiencies of electron injection from excited N3 dye into nanocryatalline semiconductor (ZrO2, TiO2, ZnO, Nb2O5, SnO2, In2O3) films
Article Abstract:
The transient absorption spectroscopy is used to measure the efficiency of electron injection from excited N3 dye adsorbed on ZrO2, TiO2, ZnO, Nb2O5, SnO2, In2O3 nanocrystalline films. The higher solar cell performance of TiO2 indicates that the reaction of conducting electron with the molecule in the solution is the key process for achieving high performance.

Electron injection efficiency from excited N3 into nanocrystalline ZnO films: effect of (N3-Zn(super 2+)) aggregate formation
Article Abstract:
The efficiency of electron injection at two concentrations through fluorescence and transient absorption measurements is studied. From fluorescence measurements, it is confirmed that the aggregates (N3-Zn(super 2+)) of N3 dyes with Zn(super 2+) ions are formed in ZnO films and electron injection from (N3-Zn(super 2+)) to ZnO films is inefficient.

Optical properties of the poly(N-benzylaniline) thin film
Article Abstract:
An investigation was made of the optical properties of the poly(N-benzylaniline) thin film by optical characterization. The optical constants such as refractive index and dielectric constant were determined from the transmittance and reflectance spectra of the thin film.
