High-Speed Laser Processing in Thin-Film Module Manufacturing

The key in thin‐film module production is reduced costs per Wattpeak (Wp). This can be achieved by cost‐effective production steps, shorter cycle times and enhanced module efficiency. Module efficiency depends on the weakest cell and active module area. That is the reason why high precision scribing is gaining in importance. Reducing cycle time is feasible by process parallelization and increasing process speed. This paper presents a summary of current laser processes in thin‐film module production.
