The ideal system for every process step – Solar wafer and cell inspection solutions from ISRA VISION / GP Solar
The demand for ever more powerful cells is growing at an almost unstoppable rate. At the same time, manufacturers need the best quality with maximum throughput to be able to produce economically.
With our unique inspection portfolio, we ensure meeting all quality requirements while envisioning full production transparency not only at the system or line level, but also across entire sites. You benefit from maximum efficiency, flexibility, and cost-effectiveness.
Our wafer and cell solutions are powered by our brand:
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.
Flawless plating improves conductivity and increases the efficiency of the solar cell. Careful quality control and monitoring are essential to ensure solar cells are uniformly plated. Manufacturers must quickly identify inhomogeneities, surface adhesion problems, and contaminations before affecting quality. This ensures high durability and prevents efficiency loss.
For high-performance cells such as IBCs (Interdigitated Back Contact), the perfect alignment of the individual layers is a prerequisite for realizing the full cell performance potential.
Even the slightest shift in the pattern or structure will result in a loss of cell efficiency.
Our inspection solutions for patterns and structures not only detect optical defects such as finger breaks but also check the correct alignment and position of the different layers in relation to each other.
Cell sorting at the end of the line is mandatory for high-value modules of homogenous color.
The CELL-Q inline inspection system checks the front or back of solar cells and sorts them into different color and quality classes according to their optical properties. In a single inspection step, CELL-Q checks every solar cell's print quality and anti-reflection coating.
Any print and color defects on all cell technologies are reliably detected. Additionally, CELL-Q identifies visible surface and contour defects to ensure that only homogeneous cells regarding color and performance are processed within one module.
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.
Central Recipe Tool
The Central Recipe Tool (CRT) allows recipe changes, including version control and approvals, to be made centrally. Identical settings are rolled out to all lines at the click of a mouse. CRT makes plants with identical quality settings comparable.
The software tool EPROMI live – Enterprise Production Management Intelligence is the latest feature of Connected PV.
EPROMI live makes data analysis much more intuitive, and flexibly adaptable to your needs. With EPROMI live, you browse your production data the way you want and wherever you want: in maximum depth of detail and comprehensive data differentiation or briefly summarized, always independent of device and location. Individually configured dashboards provide the desired information at a glance and ensure 100% production and quality transparency for PV manufacturers.
For the efficient and future-proof operation of your production systems our highly qualified service teams support you globally in all matters. We provide the implementation, maintenance and servicing as well as the analysis and optimization of your systems - quickly, reliably, 24/7.
