Technology and R&D

West Australian peer-to-peer (P2P) energy trading pioneer Power Ledger has won a lucrative contract with Alperia SpA, one of Italy’s largest renewable electricity utilities.

Australian researchers have unveiled hydrogenation technology to reduce light and elevated temperature-induced degradation in Czochralski silicon PERC solar cells. The developers say the process can minimize degradation without sacrificing performance in cells and modules.

Scientists at the University of Southern Denmark working with sodium-ion batteries found that a new electrode material incorporating iron, manganese and phosphorous could increase both the power and capacity of the batteries.

Solarwatt’s Vision glass-glass solar PV modules have pushed the technology’s resilience even further after passing Aussie cyclone testing in Darwin. The success arouses new attention to the competing riders on the bifacial wave, glass-glass and backsheets.

With solar grade polysilicon prices having plummeted in recent years, cutting down on consumption of the material has not been a priority. But strategies exist and significant savings can be made through deploying thinner wafers that use less silicon, insists a new paper published by MIT and NREL. And as manufacturers are increasingly hitting dead ends on other routes to cost reduction, this option could be back on the table for many.

UK researchers claim to have proved the viability wearable photovoltaic devices as an integral part of regular clothing. A solar-powered fabric textile was created by embedding micro crystalline silicon solar cells within the fibers of a textile through very thin copper wires. The scientists claim that the novel device can maintain its performance even after 15 domestic machine wash cycles, 25 hand wash cycles, and 6000 abrasion cycles.

This long Australia Day weekend, Australians may be considering what it takes to survive on their continent. One company based in arid Arizona has partnered with ARENA to demonstrate how solar PV can combine with other technologies to solve some of the country’s biggest problems — take a sip of Renewables 2.0. 

Curtin University research that aims to develop a new way of producing, storing and exporting green hydrogen from Australian resources, UNSW Sydney’s efforts to develop novel cathode coating materials towards more durable and powerful energy storage devices and Monash University’s investigation into phase change materials for wind and solar energy storage are among 18 new research collaborations supported by funding through the Australian Research Council.

Wellington Harbour, NZ, will see the Southern Hemisphere’s first zero-emissions electric commuter ferry.

The Australian government has opened the Critical Minerals Facilitation Office as it looks to develop a large-scale critical mineral industry to stably supply the world the critical minerals needed for batteries, solar panels, and smartphones.
