Researchers at the Ecole Polytechnique Federale de Lausanne in Switzerland and a collaborative team from Nanjing University of Aeronautics and Astronautics, National University of Singapore, University of Ioannina, and Politecnico di Milano have made significant advancements in perovskite solar cell technology. By incorporating rubidium (Rb) into the perovskite lattice structure, they were able to enhance stability and efficiency, achieving champion efficiency levels of 25.77% and 20.65% respectively. The introduction of Rb+ cations at grain domain boundaries and the lattice strain approach led to improved carrier diffusion length, lifetime, and suppression of halide phase segregation. These developments mark a promising step forward in the quest for more efficient and stable solar energy solutions.

World’s largest foldable rooftop PV system comes online in Switzerland
A 3.6 MW foldable rooftop solar installation has been inaugurated at a wastewater treatment plant in Switzerland, making it the largest of its kind globally. The system spans treatment basins, allowing the site to serve dual purposes of wastewater treatment and solar power generation. The project is expected to produce 3 GWh of electricity per year, with most of it consumed on-site. The folding-roof technology, derived from Swiss cable car engineering, automatically retracts during extreme weather events for protection. This innovative project demonstrates a pragmatic and effective way to advance the energy transition, utilizing existing space intelligently for economic efficiency and climate protection.
