Luminescent photovoltaic generator and waveguide to be incorporated with photovoltaic generator Invention relates to luminescent photovoltaic generator (1) and waveguide to be incorporated with said generator. Photovoltaic generator comprises photovoltaic element (4) and waveguide including transparent matrix (2) containing particles of inorganic luminescent material distributed therein and/or inorganic luminescent material located on at least one its side. Waveguide is associated with photovoltaic element (4) so that at using a portion of light emitted from luminescent materials is fed to photovoltaic element (4) to generated voltage therein. Note here that said inorganic luminescent material features, in at least one of UV, visible and IR bands, the absorption line width of 50 nm or larger, emission line width of 20 nm of smaller and Stokes shift of 50 nm or larger. |

Hybrid photosensitive circuit (hpc) Hybrid photosensitive circuit comprises: a diamond matrix photodetector (MPD), indium bars and silicon multiplexer sensitive sites. The structure of the MPD includes: an upper planar electrode, to which a bias voltage is applied, a diamond plate and lower electrodes of sensitive elements of the diamond MPD, from which the signal is picked. The lower electrodes are electrically connected through columns with indium arranged in a rectangular matrix with axes X and Y by sensitive elements of the silicon multiplexer. Number of indium columns on each X and Y axes must be at least two. In addition, the photodetector array of diamond in the X and Y has twice the pitch compared to the matrix of the silicon multiplexer, and lower electrodes of the diamond sensitive elements in the MPD are arranged in a staggered manner. The lower electrodes of the diamond sensitive elements of the MPD are connected electrically by indium bars only with odd or even sensitive sites of the silicon multiplexer, however, free sensitive sites of the silicon multiplexer may be used for recording visible and infrared radiations. |

Novel monomer and polymer materials Method of producing hybrid organic-inorganic material comprises the following steps: (a) peptisation of material of inorganic particles selected from oxides, sulphides, sulphates, phosphates, arsenides and arsenates of noble metals and mixtures thereof, in anhydrous sulphuric acid or hydrogen fluoride, to obtain a solution of material of inorganic particles; (b) fractionation of the solution obtained at step (a) to obtain a solution of inorganic particles having particle size ranging from 5 nm to 100 nm; (c) mixing the fractionated solution obtained at step (b) with an organic solvent; (d) reacting the mixture from step (c) with a solution of a reactive organic monomer with silane functional groups in an organic solvent. |

Photoelectric converter, imaging system Proposed converter comprises multiple photo electric converters with light-sensitive surface, isolating films, multiple light guide sections arranged atop isolating films. Note here that each light guide section directs light onto light-sensitive surface and boundary sections. Note also that each boundary section forms boundary between adjacent light guide sections and is made from material with lower refractivity compared with that of light guide section material. Note also that width of each boundary section does not exceed half the minimum wavelength of visible light, and height from bottom to top surfaces of every light guide section makes at least double maximum wavelength of visible light. |
