Flexible CuIn x Ga (1 −x ) Se 2 (CIGS) thin‐film solar cells are promising for future applications in buildings, mobility, and aerospace due to their high efficiency, lightweight, flexible nature. To achieve large‐area monolithic‐integrated modules, a scribing process, dividing into multiple series connection, is indispensable. Despite numerous merits laser can offer, further improvement required high‐quality module. Picosecond laser, generally accepted as an efficient tool suppress thermal impact, often causes problems achieving shunt‐free P1 process that isolates the back contact, typically bi‐ or multilayered Mo thin films, edge deformation source of shunt. In this study, we experimentally compare performance picosecond nanosecond lasers bilayered films different microstructures on polyimide through morphological analysis shunt evaluation selected conditions. Thermal time‐resolved measurement laser‐induced emission elucidate relevant mechanisms. It will be shown lasers, usually not preferred solution temperature‐sensitive architectures, have significant complex structures relatively large thickness, preferentially launching indirect interfacial heating mechanism optically nontransparent film–substrate combinations.
