Buffer and Passivation Layers for High-
Efficiency Tandem Solar
Cells
Tandem solar cells have gained acceptance as the most promising way to achieve a solar cell efficiency exceeding 30 percent . If these are to be siliconbased , they will require both buffer and surface passivation layers to maximise their performance . |
Competitive Advantage • Australian-based laboratory featuring an atomic layer deposition reactor with real-time feedback on synthesised material – offers an unprecedented advantage in terms of process optimisation and device integration
• Utilise an advanced , computational material science approach to identify the most promising materials before synthesising them
• Able 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
Impact • The application of a buffer and passivation layer has already resulted in creating world-record efficiency in Cd-free CZTS solar cells
|
Capabilities and Facilities • Both laboratory-scale and pilot-scale atomic layer deposition reactors to explore novel processes from low- to high-technology readiness level
• Access to both lab-scale and pilot-scale thin film deposition equipment for swift transfer from the laboratory to the factory
