Tindo joins with UNSW to boost solar cell performance

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 through advanced TOPCon technology.

The collaborations will explore Tunnel Oxide Passivated Contact solar cell technology, which in laboratory testing can achieve around 27 per cent power conversion efficiency, compared to current PERC solar cells which cannot exceed 25 per cent.

The funding comes from the Trailblazer for Recycling and Clean Energy program, a $280 million joint venture between UNSW and University of Newcastle to build new research capabilities and drive commercialisation in 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 harsh weather extremes that define many parts of Australia.

Professor Bram Hoex, one of Australia's leading solar experts heading the UNSW research team, said TOPCon presented an exciting leap in efficiency but understanding its unique features was crucial.

“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,” Hoex said.

Tindo chief executive Richard Petterson said the company was pleased to be engaged in 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,” Petterson said.

“Tindo and UNSW are optimising TOPCon technology so it produces high levels of power in all climatic conditions.”
