FIELD: physics. ^ SUBSTANCE: vertical multistage photoconverter consists of monocrystalline silicon crystals with flat diffusion p-n junctions stacked one on top of the other to form a light-receiving surface with alternating p and n regions, having the relief of the light-receiving surface in form of repeating longitudinal depressions lying such that the sectional plane of the relief, which defines its profile, is perpendicular to the direction of stacking p-n crystals. The profile of the depressions according to the invention has the shape of an open parallelogram in which the line corresponding to the bottom of the depression is parallel to the line L showing the virtual plane of the light-receiving surface - a surface without depressions, wherein the profile of depressions ensures a number of drops of the full light flux equal to 5. ^ EFFECT: high percentage of light absorption in depressions of the relief of the light-receiving surface and higher efficiency of the photoconverter overall. ^ 2 cl, 3 dwg, 1 tbl |
