The structuring of thermal-sensitive functional layers by laser patterning methods remains a challenge. The shock-wave-induced thin-film delamination (SWIFD) process is a non-thermal process of mechanically-induced film removal where the process exhibits an extraordinary application potential. Due to the spatial separation of laser ablation that is performed at the rear side of the substrate and the shock-wave-induced thin film delamination at the substrate ́s film side the thermal impact to the thin films is excluded. The SWIFD process for CIGS solar cells on polyimide substrates was studied for dependence on externally applied tension forces F. The resulting SWIFD patterns are imaged by scanning electron microscopy (SEM) to analyze the geometrical shape and the surface morphology. A reduction of the CIGS delamination threshold fluence Φth as well as a slight increase of the delaminated area A with increasing tension forces F is found. Like previous results, the area A increases with growing laser fluence and number of laser pulses and the Φth decreases with increasing number of laser pulses. The non-thermal nature of the SWIFD process, enabling a film-selective delamination of the CIGS layer (including the front contact) without damaging the Mo back contact, is also shown.
