A method of manufacturing a photovoltaic product (1) with a plurality of serially interconnected photovoltaic cells (1A, 1B) is disclosed that comprises depositing a stack with a bottom electrode layer (12), a top electrode layer (16) and a photovoltaic layer (14) arranged between said first and said top electrode layer, the bottom electrode layer and the photovoltaic layer having an interface layer (13). The method further comprises partitioning said stack into respective lateral portions associated with respective photovoltaic cells (1A, 1B), with a boundary region (1AB) between each photovoltaic cell (1A) and a subsequent photovoltaic cell (1B), and serially interconnecting mutually subsequent photovoltaic cells in a boundary region. Partitioning includes forming one or more trenches (20; 22; 23) extending through the top electrode layer and the photovoltaic layer to expose the bottom electrode layer, with at least an irradiation sub-step and subsequent thereto a mechanical fragment removal sub-step.

A method for producing a thin-film solar module with serially connected solar cells and related device. A back electrode layer is deposited on one side of a flat substrate and subdivided by first patterning trenches. An absorber layer is deposited over the back electrode layer and subdivided by second patterning trenches. A front electrode layer is deposited over the absorber layer. At least the front electrode layer is subdivided by third patterning trenches. A direct succession of a first patterning trench, a second patterning trench, and two adjacent third patterning trenches forms a patterning zone. The third patterning trenches are produced by laser ablation through a pulsed laser beam, where one third patterning trench is produced with laser pulses of higher energy and the other third patterning trench of the patterning zone is produced with laser pulses of lower energy.
