Modules

Reduce your production costs and make sure that the modules you produce are of outstanding quality.

To achieve this outstanding quality, the raw materials have to be right. Our inspection solutions for incoming cells, thin film, foil, or solar glass detect the smallest defects and faulty material. Subsequent removal saves valuable production capacity.

Cloud-based data management reduces set-up workload and significantly accelerates commissioning and recipe adjustments. 

Our solutions are supported by our brand:

Incoming cell inspection & classification

final cell sorting

Identifying faulty cells before the stringer saves valuable module production capacity. CELL-Q identifies faulty cells in time and monitors their performance class. Damage caused by transporting and handling can be claimed and rectified.

Benefits

  • Achieve homogenous modules regarding color and performance
  • Lowest overkill and underkill rates
  • Save money: Reclaim poor cells to the supplier
  • Incoming cell control before stringer

  • Contact Grid inspection: detection of print defects and monitoring of printing position

  • Color sorting:  detection of color and coating defects and cell sorting by color classes

  • Detection of other surface and contour defects 

  • Simple recipe exchange / Recipe Copy-Exact

  • Color defects: discolorations, inhomogeneities

  • Surface defects: stains, fingerprints, scratches

  • Grid defects: interruptions, thinnings, slubs, nodes, stains, smearings, mispositioning

  • Even for wafer sizes over 210 mm

  • Recipe Copy-Exact

  • LightDome Technology for the highest isotropy and homogeneity

  • Multiview Technology for the highest sensitivity in surface defect detection 

  • Image analysis on cumulative defect overlay image

  • Matrix camera technology for best metrology

PL String Inspection

Strings are the backbone of solar modules, and ensuring their quality is paramount. Photoluminescence (PL) inspection for the stringer ensures that only high-quality strings make it into the final assembly.

This cutting-edge technique employs the power of light to uncover imperfections and elevate the quality of photovoltaic strings.

At its core, PL inspection involves illuminating the cells with specific wavelengths of light, stimulating the emission of photons. This emitted light, when carefully analyzed, provides critical information about the string's material integrity and electrical characteristics. ISRA VISION’s PL inspection system LUMI-Q Scan runs laser-free, which reduces safety requirements.

Benefits

  • Reduced operational costs through minimized rework
  • Increased process yield and uptime
  • Optimized module efficiency and stability
  • Easy integration and fast ramp up
  • Detection of all relevant defects on solar strings directly in stringer
  • Laser-free and contactless inspection technology
  • Seamless integration without additional footprint (retrofit-ready)
  • Optional: Fab data management with central recipe management and comprehensive data reporting
  • Electrical & material defects: Microcracks, soldering defects, insulated areas, scratches, stains, electrical cell mismatch
  • Geometrical defects: ribbon misalignment, ribbon kink/cell shifting, string properties/geometry
  • On-the-fly measurement
  • Fast measurement speed:
    • ≥ 800 mm/s @ 3k
    • ≥1200 mm/s @ 1k 
  •   Even for wafer sizes >210 mm
