FIELD: power engineering.SUBSTANCE: offered device with photoreceiving layer for conversion of solar energy into electrical one contains, at least, one pair of substrates, each of which is designed as a strip, and, at least, one of strips is made profiled with a periodic profile in its longitudinal direction and variable profile - in a cross direction, meanwhile substrates of the same pair are connected to each other with a possibility of forming by profiles, at least, one row of cavities. The cavities can be cones and/or pyramids and/or spheres and/or spheroids and/or cylinders and/or truncated cones and/or truncated pyramids, meanwhile the cavities in different rows in a cross direction can be made with different shapes. The strip height is less than the profile height of cross and/or longitudinal sections of this strip.EFFECT: increase of efficiency of the device for conversion of solar energy by means of increase of absorption coefficient of photoreception layer, decrease of dependence of an absorption coefficient from pitch angle of fall of solar radiation at simplification of technology of manufacture, setting and operation of the device, reduction of its weight and cost.4 cl, 10 dwg |
