Abstract

The present invention relates to an arrangement having at least one solar cell, which is formed by a first sequence of differently doped layers (1, 2, 11, 12) on a substrate (6, 16), and at least one bypass diode, which is connected to the solar cell, particularly in a monolithic, series-connected solar module. The arrangement is characterized in that the bypass diode is formed by a second sequence of layers (4, 5, 13, 14), which is arranged between the substrate (6, 16) and the first layer sequence (1, 2, 11, 12).With the proposed arrangement monolithic, series-connected solar modules can be formed at a very low loss of active receiving surface, the solar cells of which are protected by bypass diodes.
