Heterojunction germanium solar cell with 8.6% efficiency
Japanese scientists have developed a heterojunction germanium solar cell with the biggest area ever achieved for the tech. It has an open-circuit voltage of 291 mV, a short-circuit current of 45.0 mA/cm2, and a fill factor of 0.656.
Australian researchers use sound waves to expand green hydrogen
Researchers from RMIT University and the University of Melbourne claim that high-frequency vibrations can release 14 times more hydrogen than standard electrolysis techniques. The discovery has ramifications for the expensive, rare materials currently used in electrolyzers.
EU’s first hydrogen pipeline to connect Portugal, Spain, France
The leaders of Spain, Portugal and France have unveiled the H2Med energy interconnection project, which will supply Europe with hydrogen. H2Med, formerly known as BarMar, will be the first green corridor to connect the Iberian Peninsula with the rest of Europe. It will be operational in 2030.
Aqueous organic flow battery for renewables storage
The Chinese Academy of Sciences has fabricated a kilowatt-scale aqueous redox flow battery with a capacity of 80 mA cm-2 over 500 cycles. The researchers claim that it is a promising candidate for large-scale energy storage.
Customizable sticker to turn solar panels into advertising billboards
An Italian startup has created a fully recyclable sticker that can be used to cover solar panels on rooftops or facades. It replicates high-definition images that can help to improve the aesthetics of solar arrays or turn PV facades into advertising billboards.
US startup develops solar-powered agricultural dehydrator
UA Technologies has developed PV-powered crop dehydration products that don’t require oil and gas fuel.
Australian researchers patent additive for perovskite’s stability problem
University of New South Wales (UNSW) researchers in Australia have discovered a low-cost way to stabilize perovskite solar cells with a triple function additive. Perovskite cells have shown the best stability results with it so far.
Growatt unveils new inverters for residential off-grid PV systems
Growatt’s new 6 kW inverters have an efficiency rating of 93% and offer 12,000 VA of surge power, up to 500 V of input voltage, and 8 kW of PV input capacity.
MIT scientists produce new organic photovoltaic fabrics
US researchers have developed a thin-film organic solar module on a vapor-deposited releasable substrate made of parylene. The device could be used as a wearable fabric, or to bring solar generation to remote locations.
Inverted perovskite solar cell with 22.15% efficiency, 83.92% fill factor
Chinese scientists have used daminozide as an interlayer and additive to make a perovskite solar cell with a p-i-n structure. It has the highest efficiency and highest fill factor for a polycrystalline, MAPbI 3-based inverted perovskite solar cell to date.
