1. A solar cell system, comprising:

  • at least one solar cell having a semiconductor layer having front and rear sides;

    first and second current collector means respectively provided on rear and front sides of the at least one solar cell;

    and means for connecting the first and second current collector means to an external element;

    wherein the first current collector means comprises a first substantially homogeneous conductive layer in contact with the rear side of said semiconductor layer, and the second currant collector means comprises a second substantially homogeneous conductive layer below said first conductive layer and separated therefrom by an insulating layer;

    said second current collector means further comprising a plurality of transverse collectors on the first surface of said semiconductor layer, the plurality of transverse collectors being connected to a longitudinal conductor extending along a longitudinal extent of the semiconductor body, and means electrically connecting said longitudinal conductor to said second conductive layer.
