DIRECTIONAL BALLOON EQUIPPED WITH A LOCAL CONCENTRATION COMPACT SOLAR GENERATOR USING BIFACIAL SOLAR CELL LINES

摘要

An airship (102) is equipped with a compact solar generator (104) for concentration to supply electrical energy to said balloon (102) in flight from solar radiation. The compact solar generator (104) comprises a first set (122) of line (s) (124, 126, 128, 130, 132) of bifacial photovoltaic solar cells, arranged parallel to a longitudinal central axis (116) of the balloon, and a solar radiation concentrator (136) for converging solar rays toward rear faces of the bifacial solar cells of the first set (122). The solar radiation concentrator (136) is a second set (156) of one or more local solar concentrator (s) (164, 166, 168, 170, 172), wherein each local concentrator (164, 166, 168, 170, 172) is matched to a corresponding line of solar cells and has a convex-shaped reflector adapted to converge solar radiation to the rear faces of the solar cells of the matched line.
