Purpose: The purpose of the paper is to examine the impact of selected dyes, organic and synthetic, on the absorbance of nanocrystalline titanium oxide. It is a major component of the working electrode of dye sensitized solar cells. Those devices belonging to the third generation of solar cells are an attractive alternative to inorganic solar cells. Therefore it intensive research on increasing their...
Purpose: The purpose of the work was to create homogenous surface layer as a result of impulse laser alloying of TiO2 and low-alloy steel. Design/methodology/approach: The surfaces of samples, coated with ceramic coating, were then irradiated with CO2 laser beam. During the work microstructure and phase investigations as well as measurement of microhardness have been carried out while the chemical...
