Dion-Jacobson perovskite solar cell with 18.82% efficiency
Scientists in China have used a fused-thiophene spacer to build a two-dimensional perovskite solar cell. It has an open-circuit voltage of 1.03 V, a short circuit current of 22.38 mA cm2, and a fill factor of 81.64%.
Tata Power awarded India’s largest solar and battery storage project
Tata Power Solar has secured the engineering, procurement, and construction contract for a 100 MW solar field with a 120 MWh battery. The project, awarded by the Solar Energy Corporation of India, will be in the state of Chhattisgarh.
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.
Partnership formed for molten salt long duration energy storage
Malta announced a partnership with Betchel to deploy electro-thermal energy storage systems that are capable of durations of 10-150+ hours.
New ‘bioinspired’ solution to battery degradation
As part of their efforts to bring lithium-ion battery degradation under control, scientists in China have looked to emulate natural defenses many organisms have evolved to reduce oxidation reactions and related damage. With an additive that ‘scavenges’ reactive particles before they can contribute to degradation, the group was able to demonstrate significantly lower electrolyte decomposition in a working battery.
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%.
Scatec lands PPA for Lesotho’s first independently built solar plant
The nation’s first independently developed solar farm will have a generation capacity of 20 MW and will sell electricity to the national utility under a 25-year contract.
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.
