A team of researchers from St. Petersburg say they can build a circuit interruptor that works directly into the current collector. The device operates via chemical reactions and would be thus more reliable than current battery monitoring system approaches.

A British-Egyptian research group has tested the use of hydrogels beads for PV module cooling. The micro-sized particles were saturated with aluminium oxide (Al2O3) water-based nanofluids and placed below the simulated PV panels. The experiment showed, according to the scientists, that the hydrogels beads were able to significantly reduce the temperature by between 17.9 and 16.3 degrees Celsius.

According to French financial newspaper Les Echos, EDF, the main shareholder of PhotoWatt, is considering closing the production in Bourgoin-Jallieu. The Auvergne-Rhône-Alpes regional council is mobilizing to save the company and announces that a regional company may acquire the module manufacturer.

The country’s Ministry of Environment has revealed that five dams have already been identified for a total of 147 MW of projects. The new target is part of South Korea’s plan to become carbon-neutral by 2050.

Scientists in the UK developed a model to explain one of the challenges to harnessing an oxygen-redox reaction in certain cathode materials for lithium-ion batteries. Based on their improved understanding of the reaction, they suggest several possible routes for further research to avoid the unwanted reactions and develop reversible, high energy density cathode materials.

A cleaning robot optimized for floating PV installations was developed by German manufacturer TG hyLIFT. Also suitable for ground-mount PV, it uses only water without any type of detergent, and is powered by batteries. The robot is now being tested at a floating PV array in Spain.

Lithium-ion battery manufacturer Energy Renaissance has welcomed a new AUD 1.5 billion ($1.2 billion) Australian government initiative to boost processing of critical minerals for batteries, solar panels, and wind turbines.

Funds from the latest part of the Biden administration’s Build Back Better pledge will go to grid modernization, carbon removal, renewable energy, and energy storage, among other technologies.

Ireland’s Fusion Fuel Green has agreed to set up a demonstrator plant in the Indian state of Tamil Nadu to generate cost-competitive green hydrogen.

PV Infolink reported a considerable increase in prices for polysilicon and wafer prices for last week. Both products saw their average price increase by over 9% compared to the previous week.
