A reduction of silver consumption in PV production is required on the way to terawatt scale. Given this, the time may have come for the commercialisation of new copper plating technologies – doing away with the need for silver in cell metallisation altogether. However, the history of plating technology is littered with cautionary tales.

Controlling the crystallisation process of perovskite thin films is one of the most challenging aspects for upscaling the solar technology but a team of Australian researchers claims to have made a breakthrough, creating next-generation PV cells that have the potential to rival the durability of silicon alternatives.

Perth-based Provaris Energy said it is moving forward with its compressed H2 carrier, while Princeton University researchers have published a study on how the transition to hydrogen-based energy systems would affect the tropospheric burdens of methane and hydrogen.

The POL Lux from Sweden is a catamaran boat design with dual electric motors and a solar canopy that can covert into a private sleeping area.

With Australia’s renewable energy share set to reach 82% by 2030, researchers from the Australian National University have launched a new online tool designed to identify the best possible locations for the development of new large-scale wind and solar farms.

Australian modular solar manufacturer 5B has secured a $20 million (USD 13.7 million) investment from the venture arm of British energy giant bp which will allow it to accelerate the development of its preassembled and relocatable modular solar technology.

Scientists in Egypt have created a self-cleaning, hydrophobic coating for solar panels that reportedly increases their efficiency by more than 30%. They used a coating solution based on polydimethylsiloxane (PDMS) and silicon dioxide (SiO2) nanocomposites, mixed with ethanol and isopropanol.

Moving with Australia’s Zeitgeist, Stuart Parry, managing director of Energy Storage Industries, is working to bring battery manufacturing onto Australian shores – and his approach is, if not novel, certainly well advanced. “It’s about being smart in how we do it,” Parry tells pv magazine Australia.

Boundary Power, a union between West Australian standalone power system (SAPS) leader Horizon Power and Ampcontrol, has installed its first off-grid system for an unnamed east coast utility in regional New South Wales.

Researchers from RMIT and the University of Melbourne have discovered high-frequency vibrations can release 14 times more hydrogen compared with standard electrolysis techniques. The discovery also has ramifications for the expensive, rare materials currently used in electrolysers. “With sound waves making it much easier to extract hydrogen from water, it eliminates the need to use corrosive electrolytes and expensive electrodes such as platinum or iridium,” research lead Amgad Rezk said.
