copper innovation
The solar cells needed to decarbonise the world will need to be more efficient, cheaper and scalable than they are today. Australia has arguably made the greatest scientific contribution to the development of solar technology, having invented the technology behind 90 per cent of all solar panels made worldwide. SunDrive is thrilled to now be working with Australia’s top deep tech and cleantech investors in developing next generational solar technologiesVince AllenCo-founder, Sundrive
Our investment
Sydney-based SunDrive Solar is working to reduce the cost of high-efficiency solar cells, while enhancing their performance and sustainability by using more abundant materials.
The CEFC has committed $7 million to SunDrive. The CEFC investment, alongside Main Sequence Ventures, was part of a $21 million Series A capital raising that attracted support from private investors including Blackbird Ventures and the private investment vehicle of Mike Cannon-Brookes, Grok Ventures.
SunDrive has grown from a small PhD project in a garage to producing some of the most efficient solar cells ever made.
The company signed a Joint Development Agreement (JDA) with global solar equipment leaders Maxwell Technologies and Vistar Equipment Technology in May 2025 to co-develop and distribute commercial-scale direct-copper plating tools to unlock the full potential of high-efficiency heterojunction solar cells. The JDA paves the way for rapid scale-up and future deployment in domestic and manufacturing lines, taking SunDrive technology from pilot-scale to commercial-scale.
The JDA follows a 2024 strategic collaboration with one of the world’s largest solar manufacturers Trinasolar and the November 2023 opening of a SunDrive production and commercialisation facility in Kurnell, NSW.
our impact
The International Energy Agency forecasts that solar PV generation capacity will more than double by the end of the decade, to 2,550 GW in 2030, with solar PV claiming a 23 per cent share of total electricity capacity.
The solar PV industry consumes approximately 10 per cent of the world’s silver, and 20 per cent of total industrial demand. This is expected to increase, highlighting the need to find alternative minerals to avoid a supply bottleneck and price challenges. Using more widely available resources like copper reduces the likelihood that silver will be mined from lower quality ores which have higher emissions.
The switch to copper
SunDrive patented technology uses copper to conduct electrical current from the solar cells instead of industry standard silver. Copper is nearly 100 times cheaper than silver and far more abundant. As such, copper has the potential to improve solar panel uptake by driving down costs.
World record
Germany’s Institute for Solar Energy Research verified in September 2021 that SunDrive panels had achieved an efficiency of 25.54 per cent, setting the world record for a commercial sized solar cell.
Revolutionary potential
Australia is a world leader in solar panel uptake with rooftop solar PV installed in about 30 per cent of Australian homes. The SunDrive technology has the potential to revolutionise onshore production of solar cells and the development of an Australian solar manufacturing industry, which will increase Australia’s resilience to supply chain disruptions and further enable the uptake of solar PV.

The SunDrive team have developed an impressive technology with origins in co-founder Vince Allen’s PhD at the University of NSW, which has been at the forefront of commercial solar technology development for decades. SunDrive’s technology has the potential to be the leading method for silver replacement in solar PV production.Ben GustManaging Partner, Virescent Ventures
