Scientists achieve 25.4% efficiency in perovskite solar cells with enhanced stability using multivalent ligands
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.
Chinese scientists build 31.13%-efficient perovskite-silicon tandem solar cell via 2D seeding agent
Researchers in China developed a novel two dimensional seeding agent to regulate crystallisation in a 1.80-eV wide-bandgap perovskite film. A perovskite-silicon tandem device made with the resulting optimised subcell achieved an efficiency of 31.13%, outperforming a control device.
