Urban land, aerosols could accelerate hail storm formation
Researchers from the U.S. Department of Energy have shown that urban landscapes and man-made aerosols have the potential to accelerate the formation of hail storms – a clear threat for PV arrays.
Australian Vanadium pushes ahead with plans for residential flow battery
Australian Vanadium is pushing ahead with plans to develop a vanadium redox flow battery for the Australian residential market, via its VSUN Energy subsidiary.
The state of the art in perovskite tandems
A new paper from scientists in China and Canada examines the recent progress in the development of perovskite-silicon tandem cells, finding a technology that’s poised for rapid commercialization, with a few research challenges still to overcome. These are primarily related to ensuring the perovskite layer can match the lifetime of the silicon cell underneath.
Sweden issues €5m call for battery studies
Researchers have just under four weeks to apply for backing for their projects, in areas including battery reuse and recycling, circular manufacturing and supercapacitors.
Herbicide may improve organic cell efficiency by up to 1.6%
Researchers in Saudi Arabia claim to have increased the efficiency of organic PV devices with diquat, a compound used in herbicide. The molecular diquat dopant increased optical absorption and the lifetime of electrical charges when light was absorbed.
Indian reliance on polycrystalline tech production leaves it trailing China
Polycrystalline PV technology, which is seeing its market share tumble on the global stage, still dominates India’s small solar manufacturing base and is emblematic of the R&D shortfalls in the sector, according to a survey of the state of the industry.
Could agrivoltaics feed demand for clean energy?
Agrivoltaics could result in more food, more energy, lower water demand, lower carbon emissions, and more prosperous rural communities, says an Oregon State University researcher. He plans to build a farm to prove the point.
JinkoSolar claims 24.9% efficiency for n-type monocrystalline cell
The result was confirmed by Germany’s Institute for Solar Energy Research (ISFH).
Zinc-air batteries with non-alkaline, aqueous electrolytes
New battery chemistry developed in Germany promises to make zinc-air batteries the storage technology of the future.
The geopolitical impact of hydrogen
In an interview with pv magazine, Indra Overland, head of the Center for Energy Research at the Norwegian Institute for International Affairs, explains how international hydrogen strategies may play out in the upcoming decades. Plans and roadmaps will not be enough to turn a hydrogen economy into reality and its success will depend on becoming cost-competitive vis-à-vis other solutions in several areas, he says.
