PV Module Development Laboratory

Co-located with the PV Module Testing Laboratory at CleanTech Park, SERIS’ 300-m2 PV Module Development Laboratory houses a fully equipped PV module production line for industry-scale PV module R&D and related services.


PV Module pilot line at SERIS


  • This machine is used for automatically soldering metal ribbons onto solar cells and interconnecting solar cells into strings. Conventional stringers are able to interconnect solar cells with up to 3 busbars. SERIS’ customised TT1800 stringer is capable of interconnecting solar cells with 3, 4, 5 or 6 busbars. Both full-size cells and half-cut cells can be processed. The TT1800 stringer enables SERIS to work on next-generation high-performance multi-busbar PV modules.

  • This station is used for assembling the various layers of materials (glass, encapsulants, strings of cells, backsheet) which will be laminated together in a subsequent process. Another task of this station is to interconnect the various strings of cells, by soldering cross connectors.

  • This machine performs the lamination process, in which all the individual layers of the module are bonded together.

  • This advanced laminator was added to the lab in 2018. It has individual chambers to perform different lamination steps, enabling more precise temperature control and ensuring good lamination quality of glass-glass modules.

  • This machine performs electroluminescence imaging of PV modules to detect cracks and other defects in the solar cells.

  • This station is used for manually repairing strings of solar cells if, for example, one cell in the string gets broken.
