The China Nonferrous Metals Industry Association (CNMIA) says wafer, cell and module prices remain stable, while industry operating rates are edging lower across leading and integrated manufacturers.

Japanese researchers used supercomputer simulations to reveal how sodium ions form clusters and move within hard carbon anodes, identifying nanopore sizes and transition regions that control diffusion and rate performance in sodium-ion batteries. Their findings offer design guidelines for optimizing hard-carbon anodes to improve energy density, cycling, and commercialization prospects.

High-resistivity silicon wafers offer superior efficiency potential but are highly sensitive to edge recombination and mechanical damage, limiting their commercial use compared to more robust standard wafers. Researchers from Longi and Sun Yat-sen University demonstrated that integrating in-situ edge passivation unlocks this potential, significantly boosting back-contact solar cell fill factor and efficiency.

The Chinese manufacturer said its 15 kW three-phase low-voltage hybrid inverter is paired with the stackable BP5000 5 kWh battery supporting up to 120 kWh. It features three MPPTs, 150% oversized PV input, and smart load management for optimized self-consumption.

Researchers in Saudi Arabia conducted a year-long simulation of fixed-tilt PV panels at different azimuth angles, finding that south-facing panels (180°) maximize energy production, while up to 45° eastward shifts cause minimal losses.

Brazilian scientists have developed a slope-based framework for agrivoltaics, finding that sites below 15% gradient offer the best balance between agricultural suitability and technical feasibility. Their review of 30 studies shows that steeper terrain can host PV systems with adapted designs, land-use limits, erosion risks, and rising installation costs.

An interlaboratory comparison between the CalLab PV Modules of Fraunhofer Institute for Solar Energy Systems ISE and Physikalisch-Technische Bundesanstalt finds the two organizations deviate by less than 0.15% when measuring the performance of photovoltaic modules. The Fraunhofer team says this is one of the most important indications as to whether their analysis is on the right track.

The Chinese supplier said the new product uses high-strength AL6005-T5 aluminum alloy and SUS304 stainless steel. It can be adjusted to a tilt angle of 0-15°.

The latest report from the International Energy Agency’s (IEA) Photovoltaic Power Systems Programme (PVPS) says second-life PV modules have the potential to reduce waste and extend the value of solar assets, but their market today remains underdeveloped and requires advances in technical qualifications, scalable reuse infrastructure and supportive policy frameworks.

The Dutch spatial atomic layer deposition equipment manufacturer has launched a new sheet-to-sheet tool for pilot production of large area perovskite solar devices on glass substrates.
