Future Fab


Future Factories: Research into new manufacturing technologies for cell and module production


  • Investigation into technologies fort he production of crystalline solar cells
  • Achievement of cell efficiencies above 20%
  • Reduction of manufacuring costs per Watt peak of 30%
  • Increase of module reliability and long term stability
  • Transfer of increased efficiencies through innovative cell concepts into the module using applicable module designs
  • Investigation into new encabsulate and bonding technologies

Time Frame:

06/ 2011 to 07/ 2014


In order to successfully transfer efficiency increases at the solar cell level (e.g. selective emitters, back surface fields, etc.) to the module, changes must be made to the entire module design.  The encapsulate and bonding technologies are investigated to minimize in particular the optical and electrical losses at the module level.

In addition to the module efficiency, higher reliability and increased yield in operation are the most important parameters for success. Fast test procedures and simulations are used to evaluate new module designs for their longevity and reliability characteristics. .
One issue that has already been identified in operation is the PID sensitivity of cells and modules, which can lead to significant production deficits. Research into the impact of cell and module designs (e.g. cell specifications and selection of encapsulate materials) on PID sensitivity will be conducted.
