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.

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.

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.

An international team of researchers led by engineering consultancy RINA Australia has completed a preliminary techno-economic study on the global potential for offshore floating PV. The results provide project cost benchmarking, country-specific economic assumptions, and a global assessment of offshore solar’s levelised cost of electricity.

Japanese electronics manufacturer Panasonic is testing its glass-based perovskite solar PV technology in office windows made by YKK AP, a construction and building materials company.

The China-based organic photovoltaics manufacturer has launched a line of indoor PV modules suitable for integration into digital office products and electronic devices.

The quality assurance service provider’s latest financial stability ranking has Tesla, Mustang Battery and Solid Power in the top three spots again, in a report that tracks manufacturers’ Altmann-Z scores over the past three years.

The quality assurance firm updated its inverter manufacturer financial stability ranking with Kstar Science and Technology, APSystems and Delta Electronics in the top three spots. It reported 19 manufacturers showing “strong financial resilience” based on Altman-Z scores.

The quality assurance provider reported India-based Insolation Energy, Waaree Renewable Technologies, and Solex Energy retained the top three positions in its Altmann-Z score-based quarterly ranking. Its analysts noted the number of companies with healthier scores increased from nine to 11.

Longi Green Energy, JinkoSolar, and JA Solar each posted significant third-quarter losses amid continued price declines and high inventory levels, raising concerns among analysts about oversupply and margin pressure across the PV supply chain.
