| description | In order to structure thin film solar cells with a transparent substrate and a transparent front electrode, the active semiconductor layer and the backing electrode are lifted off in a single step to produce the required structure pits. For that purpose, the energy required is irradiated by laser pulses through the substrate and the front electrode into the semiconductor material. The semiconductor material is thus blasted off the front electrode in the irradiated area without leaving any residues. In order to wire adjacent solar cell strips, the strips are further irradiated directly next to the generated structure pits. By reversing the phase of the semiconductor layer, low impedance areas are generated that connect the backing electrode of a first strip-shaped solar cell to the front electrode of a second strip-shaped solar cell. |
