Longi to build global service network for integrated energy strategy
China-based solar manufacturer Longi plans to support its new solar-plus-storage platform with 30 service centers across global markets by 2028.
New intrusion detection systems boost protection of SCADA systems against cyber threats
An international reserch team developed two deep learning-based IDS models to enhance cybersecurity in SCADA systems. The hybrid approach reportedly improves detection of complex and novel cyber threats with high accuracy, adaptability, and efficiency, outperforming traditional methods across multiple datasets.
Neuron Energy plans 5 GWh battery storage factory in India
India-based EV battery manufacturer Neuron Energy plans to enter the grid-scale storage market with a 5 GWh battery energy storage system (BESS) manufacturing facility in the Indian state of Maharashtra.
Copper, indium, selenium micro-islands pave the way for next-gen micro-concentrator solar cells
A German research team has developed CuInSe₂ micro-concentrator solar cells using laser-assisted metal-organic chemical vapor deposition to grow indium islands directly on molybdenum-coated glass, forming absorber arrays without masks or patterning. The not-yet-optimized micro-modules achieved up to 0.65% efficiency under one sun, with gains of up to 250% under concentrated illumination.
Spin-flip emitters could control energy pathways in singlet fission solar cells
Japanese researchers developed a molybdenum-based spin-flip emitter that efficiently harvests triplet excitons from singlet-fission tetracene dimers, producing strong near-infrared emission. This approach could boost solar cell efficiency and enable new quantum technologies by converting otherwise “dark” excitons into usable light.
BBDF 2026: Hybrid PPAs face slow uptake among industrial buyers
Hybrid power purchase agreements (PPAs) combining solar and storage are proving harder to close with industrial offtakers than standard solar deals, despite growing market interest.
Swiss startup offers lifetime guarantee for second-life batteries
Switzerland startup Evolium Technologies’ subscription-based business model offers residential battery owners a lifetime guarantee on second life batteries. The startup tests and remotely monitors each battery cell so it can alert customers when a cell is under-performing.
TNO unveils 12.4%-efficient perovksite solar tile
The Dutch research institute has presented what it describes as the world’s first perovskite-based roof tile, achieving up to 13.8% efficiency on standalone modules and 12.4% when installed on a curved surface. The flexible modules were produced using TNO’s experimental roll-to-roll platform,
France introduces cybersecurity, sustainability requirements in solar tenders
The French authorities announced they will assign 288 MW of PV in the 2026 tender for projects ranging from 100 kW to 500 kW in size and 925 MW in the procurement exercise for PV systems exceeding 500 kW. The tenders will include cybersecurity requirements as well as provisions to support European manufacturing.
Chinese researchers report 700 Wh/kg lithium-metal battery
A team from Nankai University and the Shanghai Institute of Space Power-Sources has developed a hydrofluorocarbon electrolyte enabling lithium-metal cells to operate at temperatures as low as -70 C.
