The Sudair Solar PV plant is the first project under the renewable energy program run by Saudi Arabia’s Public Investment Fund. The facility is owned by energy giants ACWA Power and Aramco, as well as electricity holding company Badeel.

German scientists have applied a new combination of cathodes and electrolytes to improve the stability of lithium-metal batteries. They fabricated a device with an energy density of 560 watt-hours per kilogram and a Coulombic efficiency of 99.94%.

A new study from Stanford University and Cornell University shows that blue hydrogen can produce more greenhouse emissions than heat produced by coal and gas. The modeling classifies blue hydrogen emissions as carbon dioxide and unburned fugitive methane, as well as lifecycle emissions linked to the mining, transport, storage, and use of methane.

Supersola has developed a 315 W, half-cut monocrystalline PV module. It costs €699 and can be coupled with other two panels to form a 1 kW residential PV system.

The solar PV module manufacturer reported strong growth for its energy storage business and an overall 105% year-on-year turnover growth. Its total module production capacity reached 19.7 GW at the end of June.

Japanese scientists have developed a new lithium-sulfur battery by using titanium oxide and titanium nitride to prevent the formation of polysulfides during the fabrication process. This allows the battery to retain 85% of its capacity after 500 cycles at 2 C.

In the second quarter of the year, more than 763 MW of solar was deployed in the eastern European country.

The quantum dots used for the device are based on methylammonium lead iodide and are synthesized within a porous silica (SiO2) matrix. Compared to its bulk counterparts, the ligand-free solar cell exhibited a more stable performance.

Helios Nordic Energy has secured another 500 MW of unsubsidized solar projects across southern Sweden.

Scientists Ayodhya Tiwari and Daniel Lincot recently spoke to pv magazine about the future of copper indium gallium selenide solar tech, which could play a key role in providing flexible, lightweight products in the building-integrated PV segment.
