A Chinese-Swedish research team has improved the performance of tin-lead-perovskite solar cells by tweaking additives and post-treatment processes. The device also showed improved stability and retained 60% of its initial efficiency after 550 hours at 85°C under maximum power point conditions. January 23, 2026 Valerie Thompson Researchers from East China Normal University and Sweden’s Linköping University have developed an alternative passivation method for tin-lead (Sn-Pb) perovskite solar cells that improves both efficiency and stability by avoiding the use of tin fluoride (SnF₂). The approach combines a lead fluoride (PbF₂) after-treatment with lead powder in the precursor. “We have identified and…

The proposed sodium-ion battery configuration is designed for stationary energy storage and is based on a P2-type cathode material and a hard carbon anode material that are said to ensure full cell performance. Electrochemical tests showed that the cathode had an initial capacity of 200 mAh/g and the anode of 360 mAh/g, with capacity retention of 42% and 67.4% after 100 cycles. January 23, 2026 Emiliano Bellini An international research team has designed a sodium-ion battery storage system (SIB) based on a P2-type cathode material known as Na0.67Mn0.33Ni0.33Fe0.33O2 and an anode based on hard carbon material made from lavender flowers.…

Gore Street Capital, parent of the UK-focused Gore Street Energy Storage Fund (GSF), has completed the first closing of a fund focused on battery storage investments, primarily in the European Union.The GS EU Fund SCSp fund has received major commitments, including the European Investment Fund and the Ireland Strategic Investment Fund, among other institutional, strategic and family office entities.Gore Street is on track for the next interim close and is targeting the final close of the fund by the end of 2026, with a target of €500 million (US$584 million).The new fund will focus on acquiring, building and operating battery…

Multinational energy company E.ON and the Peel Ports Group have commenced commercial operations on the first phase of a 25MW solar array on the roof of the Alexandra Dock warehouse, part of the Peel Ports Group’s operations in its home city of Liverpool.A total of 6,926 solar panels have been installed in the warehouse, around a seventh of the 48,000-panel system that the companies expect to install “in many more buildings across the Port of Liverpool”. In 2024, Peel Ports Group said it expects the entire portfolio to be operational by mid-2026, although at the time it said the portfolio…

Wood Mackenzie highlights a pioneering 5.2 GW solar-plus-storage project in the UAE capable of delivering 1 GW of continuous baseload power, signaling a potential shift in renewable energy deployment despite its high costs. The report also predicts strong global solar energy growth through 2030, including the rise of residential ‘balcony solar’ in the US and an increased share of solar energy in Asia Pacific and the US. January 23, 2026 Patrick Jowett Wood Mackenzie said it that a massive solar-plus-storage project currently under construction in the UAE will “redefine baseload power.” The prediction is one of three that Wood Mackenzie…

Elon Musk told the World Economic Forum in Davos that the cheapest energy for AI could come from solar energy generated in space. He also suggested that the sparsely populated areas of Spain and Sicily could serve as the “power stations” of Europe. January 23, 2026 Pilar Sanchez Molina Image: Steve Jurvetson, Wikimedia Commons, CC BY 2.0 “We are in the most interesting era in history.” This is how Elon Musk opened his speech at the World Economic Forum in Davos, speaking with BlackRock Chairman and CEO Larry Fink. Musk highlighted the potential of solar energy and battery storage in…

Technical ceramics manufacturer CoorsTek has placed the order Turn energy to construct three off-site net-metered solar projects to support the company’s operations in northeastern Colorado. The arrays, with a total capacity of 10.4 MWDC, will be built in Greeley. Once operational, the project is expected to generate approximately 20 million kWh of solar energy annually, enough to meet approximately 40% of CoorsTek’s electricity consumption at six of its Colorado facilities. CoorsTek’s ceramic products are used in a range of industries, including automotive, energy infrastructure and consumer electronics. “This partnership with Pivot Energy reflects our commitment to a more resilient and…

A research team from Osaka Metropolitan University has developed a donor-acceptor-donor molecule that can spontaneously self-assemble into nanoscale structures, providing a more stable route to built-in p/n heterojunctions in organic solar cells. January 23, 2026 Patrick Jowett Scientists from Osaka Metropolitan University have developed a molecular architecture that provides a new design strategy for the production of more efficient organic thin-film solar cells. Their donor-acceptor-donor (DAD) molecule, known as TISQ, integrates a squaraine-based p-type segment and a naphthalene diimide n-type segment within a single molecule. It is able to naturally form p/n junctions, also known as the interface between p-type…

China’s leading stationary storage battery manufacturers are accelerating the rollout of 500 Ah-plus lithium iron phosphate (LFP) cells, betting that larger sizes can reduce system complexity and increase energy density in 6 MWh-class containers, even as safety, yield and standardization challenges increase. January 23, 2026 Vincent Shaw By ESS news China’s largest stationary storage cell manufacturers have accelerated the rollout of LFP sizes above 500 Ah since 2025, positioning ‘large cells’ as a short-term path to reduce system complexity and increase energy density at the container level. CATL advertises a 587 Ah energy storage cell as part of its large-scale…

Spain’s electricity grid has lost almost 2.8 GW of available capacity in two months, raising substation saturation to 85.7% and leaving more than 5,200 facilities without spare capacity, a new analysis shows. January 22, 2026 Pilar Sanchez Molina By pv magazine Spain Spain’s electricity grid is under increasing pressure after losing almost 2.8 GW of available capacity in just two months, pushing overall saturation to 85.7%, according to the latest update of a survey by the Industry and Energy Forum and consultancy Opina 360. The study, based on data as of December 1, 2025, assessed 6,108 substations operated by Spain’s…
