Qingdao University researchers have synthesized high-performance titanium dioxide-based anode materials with excellent cycling stability, while German scientists have used operando techniques to observe how solvated sodium ions embed themselves in electrodes.

A unit of Svevind has signed an agreement to invest up to $50 billion in a project on the Caspian Sea that could produce up to 2 million tons of green hydrogen per year. Stellantis, meanwhile, has revealed plans to mass produce light commercial hydrogen vehicles.

Scientists at EPFL in Switzerland have achieved a new efficiency record for dye-sensitized solar cells. The group reported 15% efficiency in direct sunlight, and up to 30% under ambient light conditions. Their key achievement was the development of a new combination of photosensitizer materials that can absorb the entire light spectrum.

A new study has calculated that the globalized PV module supply chain has saved billions for PV installers in Germany, the US and China. It also found that if strong nationalistic policies that limit the free flow of talent and capital were implemented going forward, solar panel costs would be 20-25% higher by 2030.

Researchers from Germany have designed a tandem perovskite silicon PV cell that reportedly has lower reflection losses and improved open-circuit voltage. They demonstrated a device with submicrometre-periodic nanotextures and an improved back-reflector design.

The auction was set to contract 140 MW of distributed solar power, as part of a 520 MW tender open to thermal solar power projects for the first time. In total, 177 MW have been awarded, none of which went to thermal, 31 MW to photovoltaic, and the remainder to biomass.

At present, only a few distributors offer net-metering services in Finland, meaning that only a small share of PV systems are net-metered. In 2023, all PV systems will be offered net metering through the country’s new centralized information exchange system for the retail electricity market.

A Swedish team has inaugurated a pilot facility to mass produce algae material that can potentially boost silicon solar module efficiency by 4% and thin film by 36%. The algae are added to the encapsulant in silicon-based modules or to the anti-reflective coating on the glass of thin film modules. The team estimates the resulting modules would be 3.9% cheaper.

The Cassiopeia solar project aims to use the sunlight collected by a space satellite for terrestrial energy needs. The electricity generated would be converted to radio frequency microwave radiation transmitted to an antenna on Earth. The initial LCOE would be €48 ($47.8)/MWh, according to a UK study.
