This PhD thesis is based on publications and patent applications (1-9) to which the author contributed considerably. The list of the publications is attached at the end of this text. Systematic research of the properties of TiO2 nanoparticles brought new pieces of knowledge into syntheses of titanium dioxide nanoparticles organized in the templated structures. When the structures were used in the solar cells, their solar efficiency significantly surpassed the performance of the conventional TiO2 films. The study was focused on the engineering and optimization of parameters of the nanostructures used as anodes in the dye sensitized solar cells (DSC). Several new technical solutions have been delivered during the work on variety of TiO2 structures. First, the factors with an impact on the proper function of the TiO2 multilayer film were determined 9. and then, the layer by layer deposition technique was perfected. Introduction of phosphorus into the templated mesoporous film synthesis protocol represented significant progress. The presence of phosphorus stabilized the TiO2 surface area at a high temperature and allowed a..
