Abstract

The invention relates to a solar cell arrangement consisting of series-connected solar subcells. Said solar subcells consist of a semiconductor wafer which forms a common base material for all of the solar subcells and wherein a number of recesses are provided for delimiting the individual, series-connected solar subcells. The invention is characterised in that at least some of the recesses extend from the top surface of the semiconductor wafer, through the wafer itself to the bottom surface and in that at most some bridge segments are left in continuation of the recesses as far as the wafer edge, to mechanically interconnect the solar subcells.
