This Lessons Learnt Report provides insights into the scope and outcomes of the Project.
This project aimed to enhance and exploit novel ANU-patented technology related to the formation of polySi passivating contacts using physical vapour deposition (PVD). PolySi contacts have shown their high potential in record breaking devices and are currently being commercialized by many manufacturers to boost silicon solar cell efficiency, despite higher fabrication costs. Targeting this high cost, ANU developed PVD-based manufacturing processes, enabling simpler, safer and cheaper fabrication of polySi contacts. PVD is a non-toxic large-area deposition technique widely used in microelectronics, optics, photovoltaics, and other industries. The ANU laboratory was the first in the world to propose this new approach, demonstrating 23% efficient prototypes on laboratory scale.
