Solar cell lamination

A solar cell sheet comprising a first and a second substrate which first and second substrates are flexible and rollable, said solar cell sheet further comprising one or more self-contained solar cell units, wherein each self-contained solar cell unit comprises one or more solar cell modules, each solar cell module comprising a plurality of serially connected solar cells, wherein each of said solar cell modules comprises:

• a first substrate portion of said first flexible substrate and a second substrate portion of said second substrate,
• a plurality of first electrodes and a plurality of second electrodes arranged between said first and second substrate portions;
• at least one organic active layer arranged between said plurality of first electrodes and said plurality of second electrodes;
• wherein a continuous line or stripe of at least a first adhesive material encircles each of said solar cell units and the thickness of said continuous line or stripe of at least a first adhesive material is at most 10 μm in a direction orthogonal to said first and second substrates and wherein a plurality of discontinuous portions of a second non-conductive adhesive material is spatially arranged within each said solar cell module.
