Germany has announced plans for a new climate alliance between the world’s advanced economies, in a move that promises to transform international climate action.

Developed by French start-up Ecosun, the trailer is equipped with 15 solar panels with output of 360 W and batteries with a storage capacity of 23 kWh. It can be used for construction sites, military camps and water pumping systems.

Researchers at the Australian National University say they have set a perovskite solar cell efficiency record at 22.6%. This efficiency, however, appears to be lower than that achieved in January by a group of Swiss and Korean researchers who used quantum dots to achieve an efficiency of 25.7% in an area of 0.08cm2 and 23.3% in 1cm2.

Gelion’s zinc-bromide Endure batteries will undergo commercial tests at the 1.2 MW Montes del Cierzo testing field Spanish renewable energy company Acciona Energía operates in Navarra, in the north of Spain.

Researchers in Portugal have tested how vanadium redox flow batteries can be integrated with rooftop PV to balance the system load to ensure firm power output. They proposed a 5 kW/60 kWh battery configuration for a 6.7 kW building-integrated PV microgrid. According to their findings, the battery can be used in different energy management strategy scenarios to better complement solar photovoltaic generation.

Designed by Chinese provider Mibet, the mounting structure can be used for different crop types. The system offers a tilt angle of up to 30 degrees and can host either framed or frameless solar modules.

Western Australia-based Altech Chemicals’ plan to develop a high-grade alumina coating plant for lithium-ion batteries in Germany has taken a crucial step forward with the acquisition of an industrial site that could potentially house the facility.

Researchers in Switzerland have replaced the electron transport layers in perovskite solar cells with a thin layer of quantum dots. On an area of 0.08cm2, they achieved a record efficiency of 25.7% and high operational stability.

Fortescue Future Industries has acquired Williams Advanced Engineering for $310 million as it looks to capitalise on its critical battery technology to cut emissions from its mining vehicles. An offshoot of the Williams Formula 1 Team, Williams Advanced Engineering has already helped to develop an electric mining haul truck for Fortescue in 2021.

TOPCon solar cells are on their way to fully compete with PERC solar products, according to recent research from Germany’s Fraunhofer ISE. Efficiency gains for the TOPCon concept, however, are necessary to help it capture more market share, as production costs remain higher than those for PERC tech. A series of cost-driven strategies to make TOPCon modules advance were outlined in the study.
