The partnership, facilitated by the India Australia Technology Commercialisation Challenge Pilot Program, will combine ANU’s photovoltaics research capabilities with Indosol Solar’s giga-scale manufacturing operations in Andhra Pradesh, the companies said.
The collaboration will focus on developing advanced TOPCon cell architectures aimed at improving conversion efficiencies and resistance to degradation, with the partners targeting lower levelized cost of electricity for solar projects.
Under the agreement, ANU researchers will work with Indosol’s process teams on manufacturing processes for advanced N-type TOPCon solar cells, with the aim of accelerating the transfer of research breakthroughs from laboratory development to commercial production.
The research will target higher cell conversion efficiencies beyond standard TOPCon baselines, as well as improved resistance to light- and UV-induced degradation.
The partnership will also enable researchers from the two organisations to visit each other’s facilities, conduct joint research and undertake hands-on knowledge exchange.
ANU’s advanced cell designs will be validated on Indosol Solar’s integrated manufacturing lines in India, providing a pathway for the technology to move towards commercial production.
The collaboration is supported by the India-Australia Technology Commercialisation Challenge, part of the India-Australia Renewable Energy Partnership. The programme is funded by Australia's Department of Climate Change, Energy, the Environment and Water and delivered by CSIRO.
"Our team at ANU has a long history of driving silicon solar efficiency breakthroughs that define the global market. Partnering with Indosol Solar allows us to translate cutting-edge TOPCon innovation directly into gigawatt-scale production, ensuring high-efficiency technology makes a tangible impact on the Indian PV market,” said Dr. Rabin Basnet and Dr. Marco Ernst, Lead Photovoltaic Researchers, The Australian National University.
"Indosol Solar is committed to building a world-class, fully integrated solar manufacturing ecosystem in India. Collaborating with The Australian National University, a powerhouse in PV innovation, enables us to stay at the absolute forefront of TOPCon and next-generation solar technologies, delivering ultra-high-efficiency modules to domestic and international markets,” added Dr. Balachander Krishnan, COO, Indosol Solar.
The India-Australia Renewable Energy Partnership focuses on bilateral cooperation in renewable energy technologies and capacity building, including two-way renewable energy investment, technology commercialisation and development of the renewable energy workforce.
