MIT scientists develop semisolid zinc-manganese dioxide flow battery for wind, PV storage
MIT researchers have created a semisolid flow battery that might be able to outperform lithium-ion and vanadium redox flow batteries. It features a new electrode made of dispersed manganese dioxide particles shot through with an electrically conductive additive, carbon black.
Vershina Group secures PPA for 600 kW project in Russia
The solar array will cover around 30% of the electricity needs of a Leroy Merlin hypermarket in Volzhsky, in Russia’s Volgograd region.
Acciona signs up to supply solar for 3 GW green hydrogen project
Australia’s Stanwell Energy and Spanish renewable energy company Acciona Energia have signed a deal that could use energy generated at the proposed 600 MWp Aldoga Solar Farm to power a 3 GW green hydrogen project being developed in Queensland.
TOPCon solar module tech from Taiwan
Taiwanese solar manufacturer Motech is expanding its TOPCon module capacity to meet rising demand. Its flagship product is a TOPCon 360 W panel with a power conversion efficiency of 21.1%.
Mounting system for rooftop PV relying on large-size solar modules
Developed by Spanish manufacturer Alusín Solar, the new mounting system is claimed to be, currently, the only one on the market that provides six fixing points for a solar panel in ballast-secured structures.
Brazil has imported 7.5 GW of solar modules so far this year

CIGS solar panels for offshore PV
A Dutch consortium is testing a 20 kW pilot floating PV installation for offshore applications with CIGS solar modules developed by Swedish manufacturer Midsummer. The panels consist of 144 solar cells and measure 4 m X 1 m, with up to 485 W of capacity.
Green solvents for a 17%-efficient organic solar cell
Scientists in Sweden and China developed a solution-based process to produce organic solar cells, demonstrating efficiencies better than 17%. The process utilizes paraxylene as a solvent, which the researchers claim is less toxic and more stable than others used to reach high organic solar cell efficiencies, and with more work could be scaled up to produce large area devices.
Indian salt producer tenders 5 GW of solar
State-owned Hindustan Salts has invited developers to build and operate 5 GW of solar capacity on disused land in the Indian states of Rajasthan and Gujarat.
