METHOD AND APPARATUS FOR INSPECTION OF MULTI-JUNCTION SOLAR CELLS
摘要
A technique for providing high-contrast images of defects in solar cells and solar panels, by illuminating each cell under inspection with broadband infrared radiation, and then forming an image of radiation that is secularly reflected from the cell. Multi-junction solar cells have a metal backing layer that secularly reflects the illumination back into an appropriately positioned and aligned camera, selected to be sensitive to infrared wavelengths at which the solar cell materials are relatively transparent.
