‘Battery Atlas 2026’ maps Europe’s cell, pack and battery manufacturers
The “Battery Atlas 2026” report shows consolidation in Europe’s battery market. More than 2,000 GWh of cell production capacity was announced in 2023, but the realistic forecast for early 2026 is around 1,190 GWh, including approximately 673 GWh led by Asian companies.
Hybrid perovskite solar cell generates power from sun and rain
Researchers at ICMS in Seville have developed a hybrid perovskite solar cell that generates electricity from both sunlight and raindrops, using the photovoltaic and triboelectric effects. A fluorinated CFₓ polymer layer enables water resistance, triboelectric energy harvesting, and high light transparency without reducing solar cell efficiency.
