Advanced Surface Passivation of Silicon
Solar Cells
Combining in-depth material science know-how with advanced device simulation to optimise the performance of silicon solar cells by applying thin surface passivation layers . |
Competitive Advantage • Deep understanding of device-relevant fundamentals
• In-house capability to synthesise a wide range of surface passivation materials / stacks
• Field-leading characterisation capabilities
• First to develop a method for extracting the quantity of charge in dielectrics on doped silicon surfaces
Impact • As the surface of a silicon solar cell typically contributes the highest efficiency loss , this optimisation improves their long-term performance
Successful Applications • A pioneer in the development of aluminium oxide , which is now the de facto standard used in PERC solar cells
|
Capabilities and Facilities • Access to state-of-the-art device simulation tools and in-house laboratory
• Pilot-scale thin film fabrication capability with expertise in a wide range of surface passivation films
Our Collaborators • Leadmicro
