Abstract: A method of fabricating a non-uniformly curved photovoltaic module including multiple photovoltaic cells forming a body part of a vehicle and having differently curved areas. The method includes determining a minimum allowable bending radius of the photovoltaic cells, analysing a curvature radius of one of the photovoltaic cells being assumed to be arranged at a positioning area within the photovoltaic module, with the curvature radius being analyzed for each of multiple positioning areas along a lateral extension of the photovoltaic module, arranging the photovoltaic cells in a curvature limited configuration in which none of the photovoltaic cells overlaps a highly bended area, the curvature radius of which being analyzed to be smaller than the minimum allowable bending radius, and fixing the photovoltaic cells in the curvature limited configuration within the photovoltaic module, thereby preventing excessive bending and resulting breaking or cracking of photovoltaic cells.

Abstract: The present invention consists in a method implemented in a computer for the numerical simulation of a semiconductor device which contains (a) tunnel junctions and allows the simulation for all the working range of the tunnel junction. The method is based on a distributed model where the tunnel junction can be integrated in the simulation by means of distributed electronic circuits of a semiconductor device and, specially, of a multijunction solar cell. The said method is used to circumvent the convergence problem existing so far and allows in particular the full description of the experimental behavior of the multijunction solar cells and, by extension, of any kind of semiconductor device containing tunnel junctions.
