SWIR cameras- Dark Luminescence, a new modality for sorting high efficiency solar wafer and solar cells
19th May, 2020
Production of High efficiency solar panels depend on strict selection of the highest quality grade bare silicon wafers as well as processed cells with the lowest defect density. Current sorting inspection tools are based on CCD or CMOS cameras and are only capable of capturing the tail of electroluminescence or photoluminescence peak signals emitted beyond…
