Technology and R&D

Plans to establish Australia’s first commercial-scale solar ingot and wafer manufacturing plant near Townsville in north Queensland are advancing with developer Stellar PV providing an early glimpse of the proposed 2 GW-capacity facility.

Designed for power ratings of 29.9 kW and 50 kW with scalable capacity up to 216,9 kWh, the new system is aimed at businesses seeking flexible energy storage solutions without the complexity of installation.

A new Perspectives research study on the future of the global PV supply chain outlines how module prices, performance, and lifetimes could evolve over the next 25 years. The work reflects a collaboration among leading solar research institutions worldwide. One of the study’s authors, the director of the Fraunhofer Institute for Solar Energy Systems, told pv magazine that solar module and cell efficiencies could exceed 35% by 2050, with panel prices expected to drop by a factor of two.

New UNSW research found that about 20% of solar modules in large PV plants degrade much faster than expected. The researchers recommend holistic strategies such as robust materials, advanced designs, and proactive monitoring to decouple degradation pathways and prevent cascading failures.

JinkoSolar has signed a strategic cooperation agreement with XtalPi, an “AI for Science” platform company, to pursue high-throughput R&D on perovskite-crystalline-silicon tandem solar cells using an AI platform and quantum-physics-based models.

UNSW researchers boosted TOPCon solar cell efficiency by locally thinning the rear poly-Si layer, reducing parasitic absorption while preserving wafer integrity. The champion cell built with this approach achieved 25.10% efficiency with improved bifaciality and maintained strong passivation.

The GWh-scale long-duration energy storage project is expected to reduce curtailment in Xinjiang, a region of China with high solar and wind generation, and transmission bottlenecks. The flow battery installation is co-located with a PV plant.

UNSW researchers developed an experimentally validated model linking UV-induced degradation in TOPCon solar cells to hydrogen transport, charge trapping, and permanent structural changes in the passivation stack. They show that thicker aluminum oxide layers significantly improve UV resilience by limiting hydrogen migration, offering clear guidance for more robust TOPCon designs.

China’s Astronergy says its ASTRO N7 Pro module targets utility-scale PV plants and commercial rooftops, offering quarter-cell architecture, bifacial gains, and a 30-year performance guarantee.

The Western Australian government has opened a new round of funding under its $37 million Clean Energy Future Fund with $9 million available to back “practical” clean energy projects that help diversify and decarbonise the state’s economy.
