In recent years thin films as the nanostructured electrode material have evoked a great interest in fields of photovoltaics, energy storage, sensing, photo-electrocatalysis etc. The aim of this thesis was the preparation of functional thin TiO2 layers by chemical way using the reverse micelles templating. The sol–gel TiO2 layers deposited on the conductive ITO glass by three various deposition techniques (dip-coating, inkjet printing and spray-coating) were used as photo-anode in the three-compartment electrochemical cell. Relationships between structural properties and photo-induced conductivity of the nanostructured layers were studied.

Thin Photoresponding Elements with Frequency and Amplitude Modulations
Klusoň, Petr ; Morozová, Magdalena ; Dzik, P. ; Veselý, M.
Nanoscale templated metal oxide thin films undoubtedly appertain to the most extensively studied materials due to their optical and electrochemical properties. Their photo-induced properties arise from the semiconductor nature, especially from the ability of the light quantum absorption followed by the charge carrier generation. In order to produce metal oxide thin layer layers, the liquid sol containing also the templating bodies, and confining nanoparticles, must be coated onto a substrate. Various coating techniques have been used for this purpose, such as dip-, spin- or spraycoating. Recently a new promising deposition technique has appeared. The novel approach is usually termed piezoelectric jet material deposition or shortly material printing. In this case the ink is the specially formulated liquid purposed for transporting functional components onto the substrate surface. This technique brings the possibility of direct patterning, i.e. the fabrication of 2D patterns on the substrate without the need of any mechanical or optical masking. Material printing has been already employed for the deposition of variety functional materials.
