DEVICE FOR CONVERTING SOLAR ENERGY Russian patent published in 2015 - IPC H01L31/42 

FIELD: physics.

SUBSTANCE: device for converting solar energy includes at least a pair of substrates, each in the form of a strip, wherein at least one of the strips is profiled with a periodically recurring profile which forms a trench-like cavity, and is configured to connect its front surface with the back surface of a second strip. The strips are made of a material which allows their profiling by bending. The strip which is profiled with a periodically recurring profile which forms a trench-like cavity is configured to connect its front surface with the back surface of the second strip and to form, through their profiles, at least one row of trenches and, through strips of one pair, a flexible device for converting solar energy. Profiles of at least one row of trenches are configured to form part of a circle, and/or part of a hyperbola, and/or part of a parabola, and/or trenches with a flat, convex or concave bottom and inclined diverging side walls, wherein all trenches have outward-directed sides on the periphery of the corresponding trench that are perpendicular or inclined relative to an imaginary plane on the edge of the corresponding trench of the first strip, wherein the trenches have on their working surface a photodetector layer and the sides of the trenches have on their surface a photodetector layer or a reflecting coating.

EFFECT: higher efficiency due to the high absorption coefficient of the photodetector layer owing to a larger number of rereflections of radiation from the photodetector layer inside a trench-like three-dimensional structure, reduced dependency of the absorption coefficient on the angle of incidence of solar radiation, simple manufacturing technology, low weight.
