The further morphological investigation of nanocrystalline TiO2 films, which sensitized by suitable transition metal complexes forming a new type of molecular photovoltaic systems, the studies of new films and a new Co complexes are presented herein. Scanning electron microscopy, X-ray single crystal and powder diffraction as well as X-ray diffraction at low glancing angles using synchrotron radiation have been used. The morphology of electro- and thermodeposited Pt-layers on TCO (a), polymorphic composition of films (b), possible geometry of location of complex dye molecules on the exposed most faces of TiO2 microcrystals (c) and the crystal structure of a Co(II) complex solvated by electrolyte 4- methyl-1,3-dioxolan-2-on as a precursor of the corresponding redox-system (d) are discussed.
