Composites nanoparticles silicon carbide with lutetium diphthalocyanine were created. The size and shape nanoparticles silicon carbide, as well as their phase composition, were determined by electron microscopy. The absorption spectra of nanoparticles silicon carbide, a solution of lutetium diphthalocyanine, and a composite nanoparticles silicon carbide with lutetium diphthalocyanine were measured. Raman scattering spectra were obtained for nanoparticles silicon carbide. A comparative analysis of the absorption spectra of various samples was carried out. The effect of lutetium diphthalocyanine molecules on the optical properties nanoparticles silicon carbide was elucidated. The resulting composite of lutetium diphthalocyanine and nanoparticles silicon carbide was used as a sensitizer to create Gretzel cells. In the control Grotzel cell, lutetium diphthalocyanine was used as an absorber; in the working cell, lutetium diphthalocyanine was used in combination with nanoparticles silicon carbide. The open-circuit voltage and short-circuit current were measured under the same illumination of both Grotzel cells. Keywords: Solar photovoltaics, sensitizers, solar cells, silicon carbide, lutetium diphthalocyanine, semiconductor nanoparticles, Gretzel cells.
