We fabricated purpose-built ZnO arrays directly on ITO conductive glass and in nanochannels of polycarbonate membrane, and investigated their photoluminescence properties. The former sample exhibited only two peaks at 360 and 390 nm, which correspond to the recombination of e–h+, and UV band emission, which confirms minimal defects existed. After annealing, the second kind of samples showed an additional...
This article reports on the microstructure characterization of titanium dioxide nanodispersions and thin films made thereof for dye-sensitized solar cell devices. Structure–property relationships have been investigated mainly using electron microscopy to assess how microstructure (crystalline structure, defects) and morphological (e.g. heterogeneities, inclusions, voids) features in the electron transport...
