With solar cells, high effectiveness is a matter of quality. Ridding cells of defects to ensure this effectiveness remains a priority for the entire solar industry. The Multi-View technology developed by Isra Vision/Gp Solar’s Solar sets new standards in inspection quality, delivering crisp images of even the most challenging solar cell designs.

Isra Vision/Gp Solar’s Multi-View technology lets users experience sharply defined contours of a contact or defect. The Multi-View approach to rear inspection merges different images taken at different light wavelengths, and uses a powerful software algorithm to compute the most useful, high-contrast image. Based on this information, the Multi-View technology identifies and depicts the sharpest contours of each contact or defect. Multi-View handles all colors and even color gradients with ease – regardless of the original color of the coating surrounding relevant spots. The technology is therefore a reliable and cost-saving way to reduce false classification due to pseudo defects or undetected flaws.

Typical inspection systems use standard lighting and are limited to single image inspection, which can lead to higher rates of pseudo defects. Isra Vision/Gp Solar’s Light Dome and Multi-View technology deliver homogeneous illumination and very high isotropy. This ensures clear images so that even the tiniest details can be detected at once, ensuring reliable inspection of contacts and defects even on challenging surfaces.

CAD-style print pattern editor for any shape
The Multi-View inspection technology features a flexible CAD-style editor that defines any contact shape for the front and rear side, allowing customized inspection and extremely fast on-site implementation. Customers can avoid investing in additional programming or R&D. The editor saves the specified patterns and allows transfer between production lines and manufacturing sites.
