Evaluation of photosensitivity of materials with photocatalytic activity

The spectral, electrochemical and energy characteristics of dyes are investigated to predict their sensitisation properties and the possibility of their use for the creation of photonanomaterials that are sensitive to a wide spectral range in the near-infrared and visible regions of the spectrum. By measuring the photocurrent of films containing pure TiO₂ modified with a dye, the prospect of using polymethine dyes as sensitizers of semiconductor materials used in photovoltaics to convert solar radiation into electrical energy has been proved.
