Inspection solutions for solar wafers & cells

Detect edge distortions and geometric irregularities in less than one second cycle times. Our inspection systems sort the inspected wafers into different quality classes based on their geometric properties. Wafers that do not meet the desired quality can thus be removed before further processing – ensuring high quality for excellent module effectiveness and permanently reduced warranty costs.

The "Copy-Exact" calibration concept lets users quickly transfer inspection recipes and settings between production lines. This ensures a uniform inspection standard and reduces the system set-up workload.

Microcracks in wafers or cells can cause breakage during downstream processes or in the finished module. This can result in reduced production throughput or degraded performance in the field. Non-contact crack detection technology identifies affected wafers and cells without mechanically stressing the material. Immediate ejection lowers processing costs and boosts resource-efficient production.

Innovative inspection technology reliably and repeatedly detects visual defects such as stains, fingerprints, or chips on the surface of as-cut wafers. With its multi-image capture technology, the system can reliably detect even low-contrast defects, enabling 100% monitoring of wafer production. It classifies the wafers into different quality classes based on the data collected.

Line-scan camera technology allows on-the-fly inspection with a moving sample, enabling the highest throughput.

Texture strongly influences the color appearance and the efficiency of the finished cell. Defective and insufficiently textured wafers that are overlooked here take up valuable machine resources in the subsequent process steps.

The TEX-Q inspection system precisely monitors the cell surface for contamination and defects while checking the texturing for homogeneity and reflectivity. The cameras can also be fitted beneath the roller transport.

Homogeneous color and coating are a prerequisite for homogeneous modules.

Color and defect inspection with COL-Q immediately after the coating process ensures fast intervention in the case of color deviations. CELL-Q checks the color and coating quality during the final inspection and sorts the cells into different performance classes based on their optical properties.

Printing solar cells is one of the most expensive process steps in the cell production chain. Therefore, detecting process deviations at an early stage is crucial.

Discover the market-leading print pattern monitoring and inspect reliably at the highest line speeds. Identify and classify low-micron discontinuities and deliver cells of the highest quality.

To be an industry leader in the production of photovoltaic cells, companies must offer more than impeccable product quality: Perfectly coordinated processes across systems, production lines, and factories are the basis for maximum profitability, reliability, and short downtimes.

To achieve this, we have developed Connected Photovoltaics 4.0. This cloud-based software solution connects inspection systems, enabling consistent quality settings across all production facilities. It creates transparency, improves process control, and increases the profitability of PV production sites.

With its software features, Connected PV 4.0 meets the key challenges of PV manufacturing.
