IMPROVING THE EFFICIENCY OF LIGHT CONVERSION INTO ELECTRICAL ENERGY IN SOLAR DYE-SENSITIZED SOLAR CELL BY INTRODUCING INTO THE DESIGN OF PLASMONIC NANOPARTICLES ^{[№ 13 ' 2015]}
Work on improving the performance of solar cells is constantly are carried out. One of perspective methods to enhance the performance is to use clusters of nanoparticles with plasmonic properties in the solar cell design. In our work we investigated the effect of metal nanoparticles with a plasmon resonance on the mechanisms of electrochemical photovoltaic cells based on nanostructured titanium dioxide. The basic idea is that if the dye molecule in the dye-sensitized solar cell falls to local amplification of the metal nanoparticles electric field, then it varies greatly absorption cross section. This effect leads to the fact that the photovoltaic cells generate more free charge carriers.In our opinion, this phenomenon is one of the most important in the description of the influence of metal nanoparticles with plasmon properties on the Gratzel solar cell.Shown, that the silver nanoparticles in sample design allow generate more photocurrent. Moreover, photo current rises up, with increasing of concentration nanosilver in the cell. It is found that the sample with the highest concentration of nanoparticles short circuit current value twice the value of the current in the standard sample. The analysis shows, that maximum plasmonic nanoparticles concentration in the solar cell, increases efficiency more than 2 times in comparison with the standard sample. Furthermore, to investigate the capacitive and transport properties of the photovoltaic cell samples, was conducted a series of kinetic experiments. Shown, that presence in the structure of the cells of silver nanoparticles increases the capacity on 30 %. Furthermore, we show that the addition of silver nanoparticles in the cell considerably increases the diffusion coefficient. Since the sample with the highest concentration of nanoparticles the average diffusion coefficient is 20 % larger than the average diffusion coefficient in the standard sample.

ENHANCEMENT OF NONRADIATIVE ELECTRONIC EXCITATION ENERGY TRANSFER BETWEEN MOLECULES PLACED NEAR A CONDUCTING BODIES ^{[№ 4 ' 2011]}
In this work radiationless electronic excitation energy transfer between molecules placed near conductive bodies is investigated. A mechanism involving localized surface plasmons may be an effective mechanism for energy transfer in this system is shown. A comparative evaluation of the efficiency of direct dipole-dipole and plasmon channels of energy transfer is carried out. A dominant contribution of the plasmon mechanism in the overall rate of energy transfer in the close proximity of molecules on the metal surface and the appropriate choice of the environment dielectric properties is predicted.

INCREASE OF RADIATIONLESS ELECTRONIC EXCITATION ENERGY TRANSFER RATE BETWEEN MOLECULES PLACED NEAR A SOLID FLATE SURFACE ^{[№ 1 ' 2011]}
A radiationless electronic excitation energy transfer between molecules placed near a conductor flat surface is investigated. A mathematical model is proposed where the condensed phase boundary taken into account by introduce of an effective dipole-imagine and the medium dielectric permeability on the electronic transfer frequency in the donor molecule. A distance dependence and anisotropy characteristics of the energy transfer rate are determined in the donor-acceptor pare of adsorbates. In a purely quantum model based on the secondary quantization formalism it is showed that a mechanism of surface plasmons can be effective for the energy transfer in such systems. Comparative estimates of direct and plasmonic energy transfer channels efficiencies are made. The dominant contribution of the plasmonic mechanism to total energy transfer rate (over 1-2 power) is predicted by placed molecules near the metal surface and a weak plasmon decay.

KINETICS OF THE DIFFUSION CONTROLLED NONRADIATIVE TRANSFER OF ENERGY AMONG SMALL MOLECULAR IONS IN POLYELECTROLYTE SOLUTIONS ^{[№ 1 ' 2010]}
The paper focuses on the transfer of energy from small electron-excited ions to ions adsorbed on the surface of the charged macromolecular chain in the solution. Generalization of Smolukhovsky-Debai method was done for description of the kinetics of biomolecular reactions among sphere-like ions in solutions for the case of electrostatic field of linear poly ion. The analytical and numerical solutions of Smolukhovsky equation were obtained for the case of the balanced polyelectrolyte field.
