| Popis: | 37th European Photovoltaic Solar Energy Conference and Exhibition; 113-120 Development of novel materials for silicon solar cell production like SMART mono material with functional grain boundaries depends on the human insight and understanding of the structural and dynamic properties of the underlying crystallization process. In this work, we present an analysis and visualization process that allows for comfortable, flexible human exploration and interpretation of various crystallization-related data types ranging from per-wafer photographic images and defect measurements to segmented and 3D-reconstructed grain and defect data, by putting and combining them in a concrete, meaningful, vivid visualization context close to the spatial structure of the actual grown crystal. We address two urgent challenges for smart mono development by combining appropriate data analysis and inspection methods: (1st) analyzing crystal growth characteristics for non-destructive quality inspection and (2nd) investigating defect scenarios for identifying the best crystallization recipes. |
