UK researchers have developed organic electrode materials to integrate redox-active organic molecules into long-chain polymers. The new electrodes exhibit better cycling performance in lithium-ion batteries, with no apparent capacity decay over more than a thousand charge-discharge cycles.

Carrier will soon begin field tests for a prototype air-source heat pump for cold climates. It is designed to provide high-efficiency heating performance in harsh climates with temperatures equal or below negative 29 degrees Celsius, while being grid-interactive. The US-based heating tech specialist expects to commercialize the solution by 2024.

IEA-PVPS has standardized guidelines for O&M programs for large-scale solar plants. It defines O&M performance indicators and standard O&M operator services, as well as tools to analyze PV plant performance and safety.

Radovan Kopecek, an expert on interdigitated back-contacted (IBC) tech, says that IBC solar panels could capture more than 50% of the global market by 2030, potentially pushing TOPCon products out of competition. He told pv magazine how this transition might materialize and discussed the tech advancements that could make it possible.

Dutch scientists have achieved a record-breaking efficiency for a silicon heterojunction solar cell fabricated with a hole collector based on a molybdenum oxide (MoOx). They used plasma treatments to increase the presence of oxygen in the MoOx layer, to improve its electronic properties.

Australia’s two main tracker companies, Nextracker and Array Technologies, are launching terrain-following products to mitigate and even eliminate the need for earthworks on site, opening up previously unsuitable land for solar.

Longi has launched a series of modules featuring an all-new hybrid passivated back contact cell technology, with which it claims a maximum module efficiency of 22.8% in mass production. It will initially offer the modules in 54, 60, 66 and 72 cell formats, targeting rooftop and distributed generation applications.

State Power Investment Corp. (SPIC) has started operating the world’s first offshore floating solar plant integrated with an offshore wind turbine, at a pilot site off the coast of China’s Shandong province. It features floating PV tech from Norway’s Ocean Sun.

Solinteg is offering five versions of its new three-phase hybrid inverters, with nominal power ranging from 25 kW to 50 kW, an efficiency rating of 98.8%, a European efficiency of 98.3%, and up to 4 MPPTs.

Researchers in Singapore have developed a new light-triggered coupled oxygen evolution mechanism that builds on past oxygen evolution research. Oman, meanwhile, has announced a new hydrogen strategy.
