Abstract
The work is devoted to the investigation of interaction of cyanidin chloride (3,3’,4’,5,7-pentahydroxiflavylium chloride) and 2,3,7,8,12,13,17,18-octaethyl-21H, 23H-zinc porphyrin, which are widely used in photovoltaic cells, with particles of protonated potassium polytitanate (PPPT) applied as new semiconductor matrix material. It has been established that the values of the sorption capacity of the matrix have correlation with the data of dyes fluorescence anisotropy, but a violation of this dependence for cyanidin chloride allows suggesting penetration of dye into the interlayer spaces of the PPPT particles. The calculated values of the extinction coefficients of the dyes in the PPPT-dye system and the values of the energies of the dyes transition into the excited state indicate the prospects to use the PPPT matrix in manufacturing of photovoltaic cells.
