This method uses the analysis of images produced by electroluminescence and/or photoluminescence and makes it possible to extract a defect indicator for each cell. This indicator is then linked to the photovoltaic performance of the cells.
The Cell-LumTool software allows correlating defectiveness and yield, which will be always more strategic for all technologies aiming at excellence and high performance. Today, it is a patented R&D tool specific to the CEA, which helps to understand the yield losses on its pilot line. Tomorrow, it can be deployed in production
Cell-LumTool is designed to facilitate its deployment on any platform requiring luminescence image analysis: automation, MES, production equipment, online characterization tool etc. The current image processing time makes the tool already compatible with an industrial environment.
