New research from the University of New South Wales shows that PV module degradation varies widely with system design and location, driven by UV exposure, temperature, humidity, and atmospheric conditions. Tropical and desert regions face the highest stress, highlighting the need for climate-specific testing and system design.

Scientists at the Australian National University claim that TOPCon cells are rapidly closing the open-circuit voltage gap with HJT counterparts, now under 10 mV, while offering greater wafer tolerance and high industrial scalability. Despite slightly lower efficiency, TOPCon-based perovskite/silicon tandems can achieve a levelised cost of energy comparable to HJT-based tandems due to reduced fabrication costs, according to the researchers.

A UNSW-led team found that annealing conditions significantly affect stress, strain, and microstructure in copper-plated heterojunction solar cell contacts, with fast annealing increasing microstrain in both copper and indium tin oxide.

Solar Fabrik has introduced a 400 W red-brown glass-glass PV module designed to meet strict aesthetic requirements for historic and protected buildings, offering a 20.02% efficiency and compatibility with traditional tiled rooftops.

Building-integrated PV technology company ClearVue Technologies is a step closer to commercial deployment of its metal-backed solar panels after securing global IEC certification for the integrated rooftop system.

UNSW researchers developed a chemically selective, nitrate-based, single-sided accelerated ageing method for TOPCon solar cells that replicates the mildly acidic environment inside EVA-encapsulated modules. The proposed approach enables rapid, physically meaningful screening of front-side metallisation stability, reliably predicting module-level degradation and reducing development time and costs, according to its creators.

Tongwei is partnering with GS-Solar and Golden Solar to develop a large-scale manufacturing facility for hybrid heterojunction back-contact solar cells that combine HJT passivation, tunneling oxide and polysilicon structures used in TOPCon designs, and the grid-free front-side architecture typical of back-contact technologies.

Australian solar and thermal energy storage company RayGen says it has achieved a major international milestone with the commissioning of a 1 MW concentrated solar plant in Brazil.

Chinese clean tech manufacturer Sungrow has introduced a hybrid solar energy storage solution that integrates Sungrow’s 1+X modular inverter with a dedicated storage interface, PowerTitan 3.0 with built-in DC/DC module, and the solar-ESS Synergy Management System.

The result was certified by China’s National Photovoltaic Industry Metrology Test Center. The cell utilises a perovskite top device with MBT-ligand-controlled crystallisation on a TOPCon silicon bottom cell, achieving a void-free, high-efficiency tandem structure.
