FIELD: physics.SUBSTANCE: photovoltaic module design (1) has side walls (2), a front panel (3) with Fresnel lenses (4), a translucent back panel (5), solar cells (6) with photodetector areas (15) which are superimposed with the focal spot of the corresponding Fresnel lens (4) and lying on heat-removing bases (7), and bypass diodes. The solar cells (6) and the bypass diodes are placed at the centres of openings (8) in bars (9) made from structural metal with thickness H ranging from 0.4 mm to 0.8 mm. The front side of the bars (9) is coated by a dielectric layer (10) of thickness hand a metal coating (11) of thickness h, and top contacts of the solar cells (6) and bypass diodes are connected to said front side. The diameter of openings in the metal coating (11) over the openings in the bars (7) is smaller than the diameter of openings in the dielectric layer (10) over the openings in the bars by 0.05-0.1 mm, and the total thickness of the dielectric layer (11) and the metal coating (10) h+hsatisfies the relationship: 0.1H?h+h<0.2H.EFFECT: photovoltaic module according to the invention is highly reliable and has a long service life with high concentration of solar radiation.6 cl, 5 dwg |
