Rooftop wind energy innovation claims 50% more energy than solar at same cost
BASF is currently testing Aeromine Technologies’ patented motionless wind-harvesting system.
IEA-PVPS expects polysilicon prices to stabilize by end of 2023
The International Energy Agency Photovoltaic Power Systems Programme (IEA-PVPS) recently published a report on trends in PV applications for the 2021-22 period. Prices for polysilicon, wafers, cells and modules rose, while production capacity expanded in China and beyond.
The Hydrogen Stream: UK consortium plans 10 MW offshore wind-hydrogen facility
A group of UK companies has started working on a 10 MW wind-to-hydrogen project, American Airlines has announced a new investment in hydrogen distribution, and ACWA Power has teamed up with South Korea’s Kepco to develop green hydrogen/ ammonia projects in the Middle East.
‘Footstep tech’ for solar module cleaning
Scientists in South Korea have used a triboelectric generator and an electrodynamic dust shield to develop a panel-cleaning system that can be activated by footsteps. They said the system can remove more than 70% of accumulated dust with the pressure of just 12 footsteps.
Aerocompact launches high-elevation mounting system for rooftop PV
Aerocompact’s new CompactFLAT GS mounting structure can be installed 40 cm above rooftop surfaces, with tilt angles of 10 and 15 degrees. The company says the product is ideal for bifacial solar arrays and green rooftops.
Australian state expedites development of pumped hydro project at gold mine
A plan to build a 2 GW/20 GWh pumped hydro project at an old gold mine in the Australian state of Queensland has been declared a “coordinated project,” in order to fast-track the plan.
Selenium solar cell with optimized energy bandgap
Chinese scientists have built a selenium solar cell with an alloyed selenium-tellurium absorber, which reportedly reduces interfacial defects. Under standard illumination conditions, the device has an efficiency of 1.85%.
JinkoSolar achieves 26.1% efficiency for n-type TOPCon solar cell
JinkoSolar has set another world record for n-type solar cell efficiencies with its TOPCon technology, this time reaching 26.1%. The new record was confirmed by China’s National Institute of Metrology.
Methylammonium-free perovskite solar cell with 22.29% efficiency
Japanese scientists have built a perovskite solar cell without methylammonium to improve the device’s thermal stability. The cell showed better efficiency and stability under standard testing conditions.
Sodium-ion battery anode made from toxic hogweed
Russian researchers have transmuted poisonous Sosnowsky’s hogweed into high-grade anode material for sodium-ion batteries. The obtained material has a Coulombic efficiency of 87%, which is on par with the best reported results for hard carbons synthesized from other raw materials.
