Tindo and UNSW Collaborate on Advanced TOPCon Solar Cells
Tindo Solar, Australia’s sole manufacturer of solar modules, has announced a partnership with researchers from the University of New South Wales (UNSW) to investigate the development of TOPCon solar cells, which are anticipated to enhance efficiency significantly.
Based in Adelaide, Tindo revealed on Wednesday that it will collaborate with UNSW on two projects focused on TOPCon solar cell technology. TOPCon, short for tunnel oxide passivated contact, was pioneered in the early 1980s by Professor Martin Green at UNSW. Laboratory tests have shown that it can achieve a power conversion efficiency of approximately 27 per cent, surpassing the 25 per cent efficiency limit of current PERC (passivated emitter and rear cell) solar cells.
Historical Context and Recent Developments
Despite its origins in Australia during the 1980s, the commercialisation of TOPCon technology only commenced in the early 2010s, largely due to advancements made by the German research institute Fraunhofer ISE and, more recently, the Chinese solar sector.
With support from the Trailblazer for Recycling and Clean Energy (TRaCE) programme, the newly formed research agreement aims to combine Tindo’s manufacturing expertise and material supply chain knowledge with UNSW’s exceptional research capabilities to transition TOPCon cells from laboratory settings to practical applications.
Research Focus and Goals
The research will specifically examine how TOPCon solar cells perform under Australia’s challenging conditions, including heat, humidity, UV exposure, and extreme weather. Ensuring that these solar cells can endure real-world stresses without compromising performance is vital for lowering the levelised cost of energy (LCoE).
Professor Bram Hoex, a prominent solar expert leading the UNSW research team, expressed enthusiasm about the potential of TOPCon technology. “TOPCon represents a significant advancement in efficiency,” he stated. “The manufacturing process for TOPCon solar cells is rapidly evolving, with frequent changes that can affect the cells’ sensitivity to module components and environmental stresses. Identifying these vulnerabilities and understanding their underlying mechanisms is crucial for designing modules that are well-suited to Australia’s climate, while also opening up opportunities for wider global applications.”
Industry Perspectives
Tindo’s CEO, Richard Petterson, expressed his company’s eagerness to participate in UNSW’s efforts to develop a high-performing and durable Australian TOPCon solar cell. “While PERC solar cells are excellent for converting sunlight into electricity, TOPCon cells promise greater efficiencies and output, which is the goal we should strive for in our energy system,” he remarked.
