Researchers reveal path to fast-charging lithium-sulphur batteries

A team of Australian researchers has designed a new catalyst that has the potential to deliver a new generation of lithium-sulfur batteries that are capable of being charged in less than five minutes, instead of several hours as is currently the case.

Evaluating profitability of vanadium flow batteries

Researchers in Italy have estimated the profitability of future vanadium redox flow batteries based on real device and market parameters and found that market evolutions are heading to much more competitive systems, with capital costs down to $430/kWh at a storage duration of 10 hours.

CSIRO achieves record efficiency for roll-to-roll perovskite photovoltaic cells

The new efficiency record for fully roll-to-roll printed perovskite solar cells set by an international team of scientists from Australia’s national science agency, CSIRO unlocks new manufacturing potential. These lightweight and flexible solar cells manufactured on very long, continuous rolls of plastic can dramatically increase the rate of production and scope for deployment.

New tool to calculate efficient earthworks for ground-mounted PV

A unit of French construction group Vinci has developed a new tool to ensure efficient earthworks for ground-mounted PV systems, with a focus on optimization parameters, design restrictions, allowable slopes for mounting structures, and terrain adaptation.

Energy Vault connects commercial-scale gravity energy storage system in China

Energy Vault has connected its 25 MW/100 MWh EVx gravity-energy storage system (GESS) in China. Once provincial and state approvals are obtained to start operating, it will become the world’s first commercial, utility-scale, non-pumped hydro GESS. Meanwhile, its partners China Tianying (CNTY) and Atlas Renewable Energy have begun construction on three grid-scale GESS in China.

China’s Aiko to deliver 2 GW of All Back Contact modules to Australian shores from March

Chinese manufacturer Aiko showcased its GEN 2 N-type ABC (All Back Contact) modules at last week’s Smart Energy Expo, where the technology’s shade optimisation, enabled by its cells’ bypass diode function, made a splash. Pv magazine spoke to Aiko’s leadership about how its technology works and how the Australian market entrant plans to position itself down under.

Trina presents all-black 450 W solar modules with 22.5% efficiency

Solar technology manufacturer Trina Solar has developed an all-black version of its Vertex S+ solar module range that has a power output of up to 450 W with maximum efficiency of 22.5%.

Perovskite-perovskite-silicon tandem solar cell achieves record-breaking efficiency of 27.1%

Researchers in Singapore have built a triple junction tandem solar cell with an ultrawide-bandgap perovskite absorber integrating cyanate (OCN) ions. The cell surpassed the power conversion efficiencies previously reported for all other perovskite-based triple-junction tandems, as well as single-junction perovskite and silicon solar cells.

DAH Solar enters Australian market with anti-dust module range

Chinese solar manufacturer DAH Solar has launched into the Australian market with an anti-dust solar module with lowered frames, similar to that displayed by Longi just a few metres away during the Smart Energy Expo.
