Teaser text

Using simulations to identify interconnection and light structuring approaches that maximise electricity yield, which is a more useful determinant of the levelised cost of electricity for a location than standard test conditions.

Body Text

Competitive advantage

  • Expertise and software in optical simulation that allows for efficient matrix-based computation of electricity yield at particular locations
  • Up-to-date knowledge of state-of-the-art interconnection designs for silicon photovoltaic modules


  • Reduced LCOE by optimisation of photovoltaic modules for increased electricity yield

Successful outcomes

  • Predictions of both power and electricity yield gains for modules interconnected with wires and ribbons with light redirecting films
  • New interconnector geometries that can enhance the optical performance of photovoltaic modules
  • Collaborations with leading photovoltaic module manufacturers and producers of interconnection ribbons and light re-directing films
  • Demonstrated results identifying optical benefits of different interconnection methods (e.g. Smartwire, MultiBB, ribbons with light redirecting films)

Capabilities and facilities

  • Optical modelling software and expertise
  • Facilities for fabricating and testing modules under STC and angular illumination
