HYBRID PHOTOCONVERTER Russian patent published in 2015 - IPC H01L31/04 

FIELD: electricity.

SUBSTANCE: invention is referred to semiconductor electronics and may be used for the development of photoconverters that convert light energy into electric energy. A hybrid photoconverter comprises a dielectric substrate, insulated areas at the front face doped with an admixture of single-crystalline silicone and in each of them, close to the surface adjoining the dielectric substrate, there is a buried layer of the same conductivity as the conductivity of this area but with the bigger concentration of the dopant, and close to the surface outermost from the dielectric substrate there are two areas of different conductivity with the larger concentration of the dopant in comparison with the above areas, and the latter areas have metal connections with other elements of the photoconverter and two terminal leads connected respectively to sections of the outermost areas, at that the first terminal lead is connected to the area with the same conductivity as the conductivity of the area and contains the second dielectric substrate with insulated from each other additional areas at its front face doped with the admixture of single-crystalline silicone as the areas of the same conductivity, in each of them, close to the surface adjoining the dielectric substrate, there is a buried layer of the same conductivity as the additional area but with the bigger concentration of the dopant, and close to the surface outermost from the dielectric substrate there are two additional areas of different conductivity with the larger concentration of the dopant in comparison with the above areas; whereat at all the areas and all additional areas there are formed metal three-dimensional terminals, dielectric substrates are faced with their front surfaces towards each other and sections with the different type of conductivity in each area are connected through the three-dimensional terminals, each with the respective additional area of the opposite conductivity placed in two neighbouring additional areas while the second terminal lead is connected to the section of the same conductivity as the areas.

EFFECT: two-fold increase of voltage tapped off from the photoconverter at its lighting with the maintained area of the dielectric substrate.
