The University of New South Wales (UNSW) has partnered with Tindo on two innovative research projects aimed at advancing solar cell technology and boosting power output through the development of TOPCon (Tunnel Oxide Passivated Contact) solar cells.
TOPCon technology, first developed in the early 1980s at UNSW by Professor Martin Green, has demonstrated power conversion efficiencies of around 27 per cent in laboratory conditions — surpassing the roughly 25 per cent efficiency ceiling of the current industry-standard PERC (Passivated Emitter and Rear Cell) solar cells.
While the technology’s commercial development began only in the early 2010s, the research collaboration intends to validate TOPCon’s real-world performance under the harsh environmental stresses common across much of Australia, such as heat, humidity, UV exposure, and severe weather conditions.
Funded by the Trailblazer for Recycling and Clean Energy (TRaCE) program — a $280 million joint venture between UNSW and the University of Newcastle that supports research and commercialisation in clean energy and recycling — the partnership leverages Tindo’s expertise in solar module manufacturing and supply chains alongside UNSW’s advanced testing capabilities and photovoltaic research.
Professor Bram Hoex, leading the UNSW research team, explained the importance of understanding the technology’s specific vulnerabilities: “TOPCon presents an exciting leap in efficiency.
“But to ensure its long-term success, we have to understand its unique features, including its sensitivities to the various environmental stresses.
“The TOPCon solar cell manufacturing process is evolving rapidly, with frequent adjustments that can either positively or negatively impact cell sensitivity to module components and environmental stresses.
“Identifying these vulnerabilities and understanding their fundamental mechanisms is essential for designing modules well-suited to Australia’s climate, while also unlocking opportunities for broader global applications.”
This durability expertise will be crucial in adapting TOPCon modules for reliable long-term performance.
The collaboration is set to accelerate the commercial readiness of TOPCon solar cells, aiming to reduce the levelised cost of energy (LCOE) and promote sustainable, high-efficiency solar infrastructure capable of withstanding Australia’s diverse climate conditions.
