Inline Quality Sorting

Ensure compliance with quality standards across the company and production facilities. ISRA systems ensure that only flawless solar cells are approved for further processing.

AOI systems categorize finished solar cells into different quality classes based on their optical properties. The system reliably inspects and evaluates color and surface defects and microcracks, as well as print quality and positioning on the front and rear side of the cells. Also, a homogeneous appearance in the module is guaranteed, since only solar cells of one color class are used.


Inspection of Front Sides and Bifacial Rear Sides

Classification of front and bifacial rear sides of solar cells based on color and print quality.


Inspection of BSF and PERC Rear Sides

Inspection of full metallization and alignment of the individual print stages.


Microcrack detection

Full inline cell monitoring for microcracks.


Photoluminescence (PL) inspection for solar cells

Non-contact inspection for identifying microcracks and material defects while also determining the efficiency potential.
