Adelaide-based Tindo has joined forces with the University of New South Wales on two innovative projects aimed at boosting power output in solar cells.
The collaborations between Tindo and UNSW researchers will explore the solar cell technology known as TOPCon – Tunnel Oxide Passivated Contact – which in laboratory testing can achieve around 27% power conversion efficiency, compared to the current PERC solar cells which cannot achieve more than 25%.
The funding comes from the Trailblazer for Recycling and Clean Energy (TRaCE) program, a $280 million joint venture of UNSW and University of Newcastle to build new research capabilities and drive commercialisation in the priority areas of the Modern Manufacturing Strategy.
The first TOPCon contact was developed in the early 1980s by Professor Martin Green at UNSW, but commercial development only began in the early 2010s. The UNSW teams want to prove their TOPCon cells will perform reliably outside the lab, under heat, humidity, UV exposure, and the harsh weather extremes that define many parts of Australia.
Ensuring the high-efficiency TOPCon modules can withstand real-world stresses without performance loss is crucial to reducing the levelised cost of energy (LCOE) and promoting sustainable solar infrastructure nationwide.
“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,” said Professor Hoex, one of Australia’s leading solar experts who is heading the UNSW research team.
“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.”
Australia’s only solar module manufacturer, Tindo, brings its expertise in manufacturing processes and material supply chains, alongside UNSW’s world-class research capabilities, including advanced diagnostic tools, accelerated testing protocols and a proven track record in photovoltaic reliability.
Richard Petterson, Chief Executive Officer of Tindo, said the company was happy to be engaged in the UNSW’s development of a high-performing and highly durable Australian TOPCon solar cell.
“The PERC solar cell is an excellent technology for converting sunlight into electricity, but the TOPCon cell offers greater efficiencies and output which we should be aiming for in our energy system.
“Tindo and UNSW are optimising TOPCon technology so it produces high levels of power in all climatic conditions. Tindo has its own in-house design and engineering innovation function, but we also partner with high-level research organisations such as UNSW – it’s the blend of industry and research that will develop the next generations of solar technology.”
Mr Petterson said Tindo’s panels were designed to resist intense sunlight, coastal salt spray, wide temperature fluctuations, high humidity and hailstorms, which could cause delamination, corrosion, condensation and reduced power output over time.
