Detecting compound spots and contamination on surfaces right after the printing process, before cell firing, is essential in order to produce A-level solar cells. ISRA SOLAR VISION, the global leading supplier of sophisticated optical inspection solutions, offers a unique defect inspection system for compound spots on cell edges which will cause short-circuits when the cells enter the flashing process. Inspection at this stage helps to ensure level A quality. The new SOLARSCAN-Bevel system prevents to manufacture scrap and gives the possibility to react immediately with protective or maintenance actions. The major benefits: solar cells with best-in-class optical quality and reduced machine downtime.
In order to optimize production efficiency, to increase machine uptimes and to reduce manufacturing costs, one major goal is to detect defects such as contamination and unclean coating in the manufacturing process as early and as fast as possible. SOLARSCAN-Bevel inspects the cells after printing before firing. This enables manufacturers to clear compound spots on cell edges that could lead to short-circuits in all following cells. The additional benefit: the reliable inspection alarms the maintenance staff and signalizes that aged meshes have to be exchanged.
