Rechargeable silicon redox battery for renewable energy storage
Israeli researchers have developed a device that combines a reversible Si anode with halide cathodes and uses hybrid electrolytes to enable cell recharging. In the proposed system configuration, silicon is dissolved during the battery discharge process, and upon charging, elemental silicon is deposited.
Solar is the cheapest power, and a literal light-bulb moment showed us we can cut costs and emissions even further
New research suggests we might be able to rethink the type of silicon needed to make high-efficiency solar cells, say researchers from the CSIRO, UNSW and Oxford University.
NT’s first hydrogen-fuelled generator piloted by Charles Darwin University
The Northern Territory is set to install its first hydrogen energy storage system as part of a pilot being operated by the Charles Darwin University in Darwin.
CSIRO steps in to provide expertise for SA natural ‘gold’ hydrogen rush
West Australian natural hydrogen startup H2EX will work with Australia’s national science agency, the CSIRO, to study natural hydrogen systems in South Australia’s Eyre Peninsula, describing the research as a “pivotal first step” for the nascent industry. Natural hydrogen proponents believe projects could deliver some of the world’s cheapest hydrogen quickly and with a minimal footprint.
Cooling down solar modules with cotton wicks immersed in water
The novel technique consists of attaching cotton wicks immersed in the water (CWIWs) to the backside photovoltaic module. The water is supplied to cotton wicks from top to bottom by gravity which the scientists said helps the effective absorption of cotton and reduces water consumption.
Reverse bias – a hidden challenge for perovskite solar cell stability
Research from renowned PV scientist Martin Green and colleagues at UNSW reveals that perovskite solar cells may struggle to deal with reverse-bias caused by uneven shading or other issues likely to appear in the field. Both the reverse-bias itself and resulting build up of heat can cause several of the materials commonly used in perovskite solar cells to degrade, and these issues have received only limited attention in research published to date. Solutions, however, are at hand.
PV industry needs 12 times more polysilicon production capacity by 2050
New research from the University of New South Wales (UNSW) predicts cumulative polysilicon demand of 46-87 Mt will be required to achieve 63.4 TW of PV installed by 2050.
‘Not valued clearly at present’: ARENA-backed study looks into how to better incentivise storage investment
Melbourne’s Monash University will conduct a $1.18 million study into alternative market designs which better support energy storage technologies and drive clearer investment signals.
Homes with solar sell for $125,000 more on average
Energy efficient homes, like those with solar panels, fetch, on average, a premium of over 17% in Australia – though that figure grows to 28.9% in Queensland and 24% in Victoria, according to a report from real estate company Domain.
New kind of black silicon shows improved light-trapping properties
Scientists in Russia have developed a new wide-band optical absorber called ‘black silicide’ which they claim is more adjusted to match AM-1.5 solar spectrum with theoretically higher photogenerated current density. It could be used for tandem operation in photovoltaic devices.
