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.
UNSW team sets efficiency record for emerging solar cell material
Researchers at the University of New South Wales have achieved a record-setting power conversion efficiency with solar cells made from antimony chalcogenide, an emerging PV material regarded as a strong candidate for next-generation solar technology.
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.
Study shows some POE encapsulants pose threat to TOPCon solar modules
University of New South Wales researchers found that some POE encapsulants can trigger severe corrosion in TOPCon solar modules, causing up to 55% power loss under damp-heat conditions. Their study highlights that module reliability depends on the exact encapsulant formulation, not just the polymer type.
Tesla offers new all-black solar module for residential applications
The launch of the new product suggests United States-based manufacturer Tesla could renew its focus on residential solar and expand lease options with its Powerwall residential battery energy storage offering.
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.
Stellar reveals scale of 2 GW solar ingot and wafer manufacturing plant
Plans to establish Australia’s first commercial-scale solar ingot and wafer manufacturing plant near Townsville in north Queensland are advancing with developer Stellar PV providing an early glimpse of the proposed 2 GW-capacity facility.
Tongwei unveils 770 W TOPCon PV module with 24.8% efficiency
The Chinese manufacturer has unveiled its new TOPCon bifacial TNC3.0 module. The 1,500 V, IP68-rated panel offers over 85% bifaciality, a 0.26%/C temperature coefficient, and a 30-year warranty guaranteeing 88.85% output.
Solar module efficiency could exceed 35% by 2050
A new Perspectives research study on the future of the global PV supply chain outlines how module prices, performance, and lifetimes could evolve over the next 25 years. The work reflects a collaboration among leading solar research institutions worldwide. One of the study’s authors, the director of the Fraunhofer Institute for Solar Energy Systems, told pv magazine that solar module and cell efficiencies could exceed 35% by 2050, with panel prices expected to drop by a factor of two.
How to avoid ‘long tail’ effects in large-scale PV plants
New UNSW research found that about 20% of solar modules in large PV plants degrade much faster than expected. The researchers recommend holistic strategies such as robust materials, advanced designs, and proactive monitoring to decouple degradation pathways and prevent cascading failures.
