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.
Smart Commercial to roll out prefabricated vertical rooftop PV system
Smart Commercial Energy has unveiled a new prefabricated vertical rooftop solar system for the Australian market as part of a collaboration with Norwegian clean energy company Over Easy Solar.
Researchers achieve record perovskite solar module stability under light, heat, and UV stress
An international research team has developed a new two-dimensional perovskite interlayer based on a co-crystal engineering strategy for more robust perovskite films. It demonstrated improved performance in small area perovskite solar cells and, in a 48 cm2 module, contributed to retain 95% of initial efficiency after 5,000 h.
The impact of transparent conductive electrodes on perovskite-silicon tandem solar cell performance
An Oxford researcher has found that transparent conducting electrodes can reduce perovskite–silicon tandem solar cell efficiency by over 2%, with losses linked to electrical resistance, optical effects, and geometric trade-offs. Using a unified optical–electrical model, the scientist showed how careful optimisation of TCE stacks, coatings, and cell design is critical to closing the gap toward the 37%–38% efficiency frontier.
