Embodiments of the present invention generally relate to an automated production line using a common laser scribe module for providing consistent scribe lines in multiple layers during the formation of thin film photovoltaic modules. The common laser scribe module includes a plurality of identical, programmable laser tools configured to emit radiation at a common wavelength. Substrates flowing through the production line are tracked by a system controller, which identifies available laser tools within the common laser scribe module and routes substrates to available tools for scribing features in one or more layers disposed on the substrates. The system controller also sets and controls laser parameters, such as power, pulse frequency, pulse width, and laser pattern, in order to accurately and consistently produce scribed lines in the appropriate material layer of the substrate.
