Let’s say you want to encourage more drivers to shift to battery-electric vehicles. What’s the best way to do it?

Norway’s Photoncycle has raised $24.8 million to develop a seasonal home energy storage system that converts excess solar power into ammonia-based hydrogen for winter use.

Swedish researchers developed two novel single-axis solar tracking strategies that dynamically adjust panel tilt based on crop light requirements, balancing photosynthesis and energy production. One strategy prioritises daily light integral targets before shifting to energy capture, while the other uses the light-response curve to optimise photosynthesis, offering improved dual-use efficiency compared with conventional tracking methods.

Scientists in Hungary found that ground-mounted solar modules at an intermediate elevation of 1.1 metres achieve the highest efficiency and power output due to improved airflow and reduced cell temperature.

The latest report from the International Energy Agency’s Photovoltaic Power Systems Programme says second-life PV modules have the potential to reduce waste and extend the value of solar assets, but their market today remains underdeveloped and requires advances in technical qualifications, scalable reuse infrastructure and supportive policy frameworks.

The Portuguese company said its new Drone AgroPV Cleaning Agent is scheduled for release in June. It has a safe formulation for crops and soil.

Norwegian fire safety specialist Bridgehill has developed a fire-resistant roofing membrane designed for use beneath rooftop PV systems. The company says the product is intended to limit heat transfer and flame spread in commercial and industrial installations subject to strict fire safety and insurance requirements.

An international study finds that successful agrivoltaic projects require farm-specific, holistic co-design that integrates solar layout with agricultural mechanisation from the earliest planning stages. Without proper alignment between machinery, crops, and solar systems, agrivoltaics risk major land loss, lower field efficiency, and higher operating costs, undermining farm profitability.

The Ariya demonstration vehicle features 3.8 m² of Lightyear’s custom solar panels integrated across the hood, roof, and tailgate. Testing showed that the car could generate 0.5 kWh of solar energy during a 2‑hour, 80 kilometer trip, delivering up to 3 kilometres of range at no extra cost or charging time.

Researchers have used multivalent amidinium ligands to boost perovskite solar cell efficiency to 25.4%, achieving over 95% stability after 1,100 hours at 85 C. The proposed approach enables controlled low-dimensional passivation layers, offering a practical route for durable, large-area perovskite devices.
