The Swedish thin-film solar specialist produces 50 MW of modules at its Bari facility, using its proprietary DUO system for cell manufacturing. The company says it sources all materials from the EU and other countries in the global North.

Data from the Swedish Energy Agency finds there are now approximately 314,600 grid-connected solar plants in Sweden, the majority of which are systems smaller than 20 kW. The agency’s latest analysis also notes the rate of installations is slowing.

German and Swedish researchers have found that rapid temperature cycling degrades perovskite cell performance through thermally induced stress and phase transitions, while also identifying organic spacer molecules that can enhance structural stability.

Researchers in Sweden developed a bifacial chalcoprite solar cell using a titanium-doped indium oxide (ITiO) back contact, achieving 68% bifaciality. The device is able to maintain strong front-side performance with around 15% efficiency, 595 mV open-circuit voltage, and 75% fill factor.”

Sweden’s Ionautics has advanced its platinum-based hydrogen catalyst toward full-scale industrial production, while thyssenkrupp nucera has signed contracts for 300 MW of alkaline electrolysis capacity in Spain and 260 MW in India.

Swedish thin-film solar manufacturer Midsummer has secured its largest-ever order for production equipment, covering a complete solar cell factory. It follows an initial order in May 2025 for a 15 MW line producing thin-film copper, indium, gallium and selenide (CIGS) solar cells.

Researchers in Sweden have developed an air-based photovoltaic-thermal system that can preheat ventilation air and domestic hot water, cutting district heating demand by up to 16% for ventilation and 7% for hot water while also reducing peak heating loads in cold Nordic climates.

Swedish engineering company Alfa Laval and South Korea’s Institute for Advanced Engineering (IAE) plan to build a liquid air energy storage (LAES) facility designed to liquefy up to 10 tons of air per day for long-duration grid balancing.

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 prioritizes daily light integral targets before shifting to energy capture, while the other uses the light-response curve to optimize photosynthesis, offering improved dual-use efficiency compared with conventional tracking methods.

Researchers in Sweden developed a new methodology to optimize agrivoltaic systems across Europe, showing that row pitch, system type, and panel orientation must be tailored to local climate, crops, and regulatory constraints.
