The lightweight and flexible cell was built by Estonian researchers with microcrystalline powders. The device is claimed to be the most efficient solar cell fabricated with a semiconductor compound known as Cu2CdGe(SxSe1−x)4.

The University of New South Wales is leading a new research project to determine how rooftop solar PV and other distributed energy resources, including small-scale batteries, can be integrated into Australia’s power grid.

Arvind Shah, a professor at École polytechnique fédérale de Lausanne, and Meyer Burger former Chief Innovation Officer Sylvère Leu recently spoke to pv magazine about the future of heterojunction PV modules. They said the tech is mature and can now compete on cost with PERC panels in projects – particularly in hot, humid environments.

The Recommended Practice guide, on top of describing the most common requirements for building a floating PV array, provides a series of technical guidelines for electrical safety, anchoring and mooring issues, operation and maintenance, and specific plant design that can withstand site-specific environmental conditions.

Two recent studies have separately shown that many scenarios assessing global decarbonization pathways are still predicting too-low future PV capacity and too-high LCOEs for the solar technology. The researchers analyzed scenarios provided by scientific researchers, government bodies and non-governmental organizations, including the United Nations’ Intergovernmental Panel on Climate Change (IPCC), the U.S. Energy Information Administration (EIA), the European Commission, the Indian government, the International Energy Agency (IEA), and the International Renewable Energy Agency (IRENA), among others.

New research shows that renewables plus batteries could offer Australia’s electricity grid the same energy security as coal and gas generators, prompting calls for regulatory changes.

U.S. researchers have discovered that long-duration energy storage technologies could make the decarbonization of the electricity system more affordable and reliable.

German start-up Phytonics has developed the film by taking inspiration from nanostructures in plants. In solar cells, the film enables a broader absorption spectrum and a higher angle of light-incidence tolerance.

U.S. researchers are using a data fusion approach to identify the most stable perovskites for PV cells. Their machine-learning method combines perovskite test results with first-principles physical modeling to identify the best candidates.

Australian scientists have achieved a new breakthrough in carbon capture and storage. Their novel electrochemical process can store carbon dioxide in water with the power of solar or wind, while also producing by-products such as green hydrogen and calcium carbonate – perhaps the key to decarbonizing the cement industry.
