PHOTOVOLTAIC CELL ARRAY WITH MECHANICAL UNCOUPLING OF THE CELLS FROM THE CARRIER THEREOF

A solution is provided for reducing the mechanical coupling of the photovoltaic array of the solar generator in relation to the latter's support substrate. Indeed, the photovoltaic cell is very slender (a few tens of microns) and very fragile. When the latter is glued onto a substrate, it undergoes all the geometric deformations due to vibrations but especially to thermo-elastic effects, possibly leading to the breakage of the cells. The cell is fastened via a flexible system making it possible to decouple the cell from the deformations of the substrate while ensuring sufficient radiative coupling of the cell toward the substrate to avoid heating thereof in flight and loss of effectiveness thereof. The solution includes using photovoltaic cells with high-emissivity rear face (rear use of a metallization or kaptoning of the Ge or Ag substrate) that is fixed with the aid of Velcro onto the substrate.
