Huawei unveils FusionSolar 9.0 platform with AI, grid-forming tech
Huawei’s FusionSolar 9.0 is a new integrated solar-plus-storage platform featuring smart inverters, AI-driven management, and grid-forming capabilities to turn solar plants into active grid-support assets. It boosts efficiency, reduces costs, and enhances stability in weak grids with high renewable penetration, according to the company.
Antimony vs. phosphorous doping in solar wafer manufacturing
An international research team comprising scientists from Chinese module manufacturer Longi has investigated the resistivity distribution of antimony- and phosphorous-doped wafers used in solar cell manufacturing and have found that they offer comparable mechanical strenght. However, their work also showed that antimony-doped wafers have a more uniform resistivity, with a slight increase near the tail end.
Astronergy and JA Solar end global patent disputes with cross-licensing deal
Astronergy and JA Solar ended all global litigation and signed a cross-licensing agreement covering tunnel-oxide passivated contact (TOPCon) solar cell patents, resolving a major intellectual-property dispute affecting markets in Europe and beyond.
JinkoSolar achieves 34.76% efficiency for perovskite-silicon tandem solar cell
JinkoSolar says it has increased the efficiency rating for its perovskite-silicon tandem solar cells from 34.22% to 34.76%, confirmed by China’s National PV Metric & Testing Center (NPVM).
All-perovskite tandem solar cell with dipolar passivation achieves 30.1% efficiency
Researchers in China have developed a dipolar passivation method that reduces defects and improves charge transport in solar cells based on narrow-bandgap tin lead perovskite. The approach has enabled the fabrication of all-perovskite tandem solar cells with efficiencies of around 30% and enhanced stability,
Chinese PV Industry Brief: January-October solar additions reach 252.87 GW
