Teaser text

It is quite well accepted that tandem solar cells are the most promising way to achieve a solar cell efficiency in excess of 30%. If these are to be silicon based, they will require both buffer and surface passivation layers in order to maximise their performance.

Competitive advantage

  • The only laboratory in Australia that has an atomic layer deposition reactor with real-time feedback on the synthesised material, offering unprecedented advantages in terms of process optimisation and device integration
  • Use of an advanced, computational material science approach to identify the most promising materials before synthesising them
  • Ability to perform atomic-scale engineering using atomic layer deposition
  • Real-time insight and control of thin film growth and its correlation to final device performance


  • The application of a buffer and passivation layer has already resulted in creating world-record efficiency in Cd-free CZTS solar cells.

Successful outcomes

  • A wide range of binary and tertiary compound thin films have been developed for integration into thin film solar cells

Capabilities and facilities

  • Both laboratory-scale and pilot-scale atomic layer deposition reactors to explore novel process from low- to high-technology readiness level
  • Access to both lab-scale as well a pilot-scale thin film deposition equipment for swift transfer from the laboratory to the factory

Our partners

  • Working together with various leading worldwide research groups to test thin films at the solar cell device level
