FSS 4Flexible Spring Suspension 4

INNOVATIVE NEW Probing Solution for R&D and Mass Production
of All Cell Designs Providing Structure Guarantee Over 1 million contacts

Background

Sample of Bus Bar Less PV cell

Sample of Multi Bus Bar PV cell

Sample of Shingled PV cell

Various new electrode patterns and large cell size being developed for the purpose of improvement of PV cell efficiency and decrease of production cost:
  • Busbar less ( No Busbar )
  • Multi Busbar ( Fine Busbar close to Finger electrode width)
  • Shingled cell ( Electrically independent electrode)
  • 210mm SQ Size Cell
Major and Common concern that Conventional pin type probe bars cannot cope up with this new trend in both production line and R&D to measure stable and precise IV characteristics.
Solution
INNOVATIVE probing technology of “FSS 4”

Feature of FSS 4 technology

  • Change to Line Contact with Stable 4 Wire Connection Structure from Pin contact, enabling precise I-V Curve Measurement for the Innovative cells of the various design such as Busbar-less, which Conventional Pin-Probe cannot achieve.

  • Soft touch contact of 0.16N/single strip (35N/single FSS 4 for M2 cell) to the finger electrodes by the unique structure.

  • High Reliability probe structure because of Monolithic Construction with No Sliding motion.
    Thinner (1.2mm) than the Conventional Pin-Probe reducing Shade on cell.

  • Excellent Reproducibility better than ± 0.02% for Isc and Voc, better than ± 0.05% for Pmax and better than ± 0.04% for FF, and better than +/- 0.012mΩ for Rs.

  • Benefit to Total Cost Performance because of Long Mechanical Life Warranty of 1,000,000 times. The FSS 4 is designed to have Comparable or Better Durability than the former types of FSS,
    which has achieved Over 10 million times of Mechanical Durability at In-House Pro-Long
    Test and Over 4 million times in the Actual Production Line.

  • Equivalent Electrical Characteristics to Pin-Probe for Bus-Bar cell and FSS 4 can be used for the Conventional Bus-Bar cell as well.

  • Excellent Compatibility with Pin-Probe in Production Line for Easy Introduction.

  • The FSS 4 can cope up with the Large Size cell up to even Over M12 210mm SQ.

  • Patent for the structure of FSS 4 is pending. Partially Approved.

  • Unique Spring Structure enabling
    Excellent and Soft Touch Contact
    Line contact to all finger electrodes
    by Half Pitch Staggered design
  • Reproducibility of I-V Measurements (Dynamically Measured, 6” BBL HJT Cell)

  • Durability
    Mechanical Durability : Over 10 Million Times
    Actual Mass Production Conditions : Over 4 million times

  • Comparison with Pin-Probe (Electrical Characteristics)

  • Compatibility with Pin-Probe (Production Line)

FSS 4 Line Up

Available for cell size from M2 157mm SQ to M12 210mm SQ and Over 210mm SQ as well. The FSS 4 can accommodate Any Size of Large cell Over 210mm SQ.
