New research from the University of New South Wales shows that PV module degradation varies widely with system design and location, driven by UV exposure, temperature, humidity, and atmospheric conditions. Tropical and desert regions face the highest stress, highlighting the need for climate-specific testing and system design.

Output from Australia’s utility-scale solar assets jumped almost 22% in the past 12 months with new data showing the country’s large-scale PV assets generated 1.82 TWh of clean energy last month.

Scientists at the Australian National University claim that TOPCon cells are rapidly closing the open-circuit voltage gap with HJT counterparts, now under 10 mV, while offering greater wafer tolerance and high industrial scalability. Despite slightly lower efficiency, TOPCon-based perovskite/silicon tandems can achieve a levelised cost of energy comparable to HJT-based tandems due to reduced fabrication costs, according to the researchers.

A UNSW-led team found that annealing conditions significantly affect stress, strain, and microstructure in copper-plated heterojunction solar cell contacts, with fast annealing increasing microstrain in both copper and indium tin oxide.

The Australian Energy Council has released its Energy 2050 report addressing what policy makers and industry might do to deliver a net zero system, while balancing affordability, reliability and sustainability.

LONGi has launched LONGi ONE, an integrated solar-plus-storage product strategy for grid-scale, and commercial and industrial projects, which will be supported by a growing network of 30 new service centres opening in key locations globally by 2028.

Trucking company New Energy Transport says electric road freight is possible now and already commercially viable in Australia after completing what it is calling the country’s first fully electric ‘end-to-end’ heavy road freight delivery.

UNSW researchers developed a chemically selective, nitrate-based, single-sided accelerated ageing method for TOPCon solar cells that replicates the mildly acidic environment inside EVA-encapsulated modules. The proposed approach enables rapid, physically meaningful screening of front-side metallisation stability, reliably predicting module-level degradation and reducing development time and costs, according to its creators.

Tongwei is partnering with GS-Solar and Golden Solar to develop a large-scale manufacturing facility for hybrid heterojunction back-contact solar cells that combine HJT passivation, tunneling oxide and polysilicon structures used in TOPCon designs, and the grid-free front-side architecture typical of back-contact technologies.

A multibillion-dollar pipeline of electricity transmission upgrades is being proposed by South Australia’s network operator ElectraNet as it seeks to keep pace with “unprecedented” levels of connection demand.
