“…In this work, we obtained a stable Grötzel cell with embedded silicon carbide nanoparticles in Lutetium Diphthalocyanine as a photosensitizer with improved power and efficiency characteristics. The data obtained by us on the COP and power of the Gretzel cells are also in good agreement with the data of other authors [15].…”

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.

“…Additionally, it is worth noting that the distribution of the inorganic component in the polymer matrix is quite uniform without significant aggregation, which may indicate the presence of the appropriate physicochemical interaction between them. This is especially important for the manufacture of appropriate fluorescent matrices based on TiO 2 , when the latter is doped with a luminescent impurity [65][66][67].…”

The influence of poly(titanium oxide) obtained using the sol-gel method in 2-hydroxyethyl methacrylate medium on the viscoelastic and thermophysical properties of interpenetrating polymer networks (IPNs) based on cross-linked polyurethane (PU) and poly(hydroxyethyl methacrylate) (PHEMA) was studied. It was found that both the initial (IPNs) and organo-inorganic interpenetrating polymer networks (OI IPNs) have a two-phase structure by using methods of dynamic mechanical analysis (DMA) and differential scanning calorimetry (DSC). The differential scanning calorimetry methods and scanning electron microscopy (SEM) showed that the presence of poly(titanium oxide) increases the compatibility of the components of IPNs. It was found that an increase in poly(titanium oxide) content leads to a decrease in the intensity of the relaxation maximum for PHEMA phase and an increase in the effective crosslinking density due to the partial grafting of the inorganic component to acrylate. It was shown that the topology of poly(titanium oxide) structure has a significant effect on the relaxation behavior of OI IPNs samples. According to SEM, a uniform distribution of the inorganic component in the polymer matrix is observed without significant aggregation.

In this paper the results of a study of the effect of the concentration of silver nanoparticles in films of titanium dioxide nanorods on their photocatalytic activity are presented.Titanium dioxide nanorods with a rutile structure was obtained usingthe method of hydrothermal synthesis. Due tochanging with the amount of substance of the transition metal silver salt (AgNO3) and chemical reduction on the surface of the titanium dioxide nanorods, Ag nanoparticles of different concentrations were obtained. The photocatalytic activity of the samples was assessed by the amount of photocurrent obtained from a unit of film surface and photodegradation of methylene blue dye when illuminating the surface with a light source of a Xenon lamp.Surface morphologies and energy dispersive X-ray studies showed that Ag nanoparticles were uniformly distributed and anchored on the titanium dioxide nanorods surface.
