Solar module prices lagging behind soaring silver costs
Solar manufacturers are facing rising cost pressure as silver paste now accounts for up to 30% of total cell production costs. OPIS analyst Hanwei Wu tells pv magazine that module producers currently have limited ability to raise panel final prices, which is accelerating efforts to reduce silver use across all mainstream cell technologies.
Chinese scientists push selenium solar cells beyond 10% efficiency
Researchers at the Chinese Academy of Sciences have set a world record for selenium solar cells, achieving 10.3% efficiency for the first time above the 10% threshold. The breakthrough was enabled by optimized charge-selective contacts, light-driven crystallization, and post-deposition annealing, producing stable devices with a 1.03 V open-circuit voltage.
Swiss researchers improve electrolyte design for long-life solid-state batteries
A Swiss research team has developed a low-temperature sintering and interface-coating process that significantly improves the durability of argyrodite-based solid-state batteries. The approach delivers high ionic conductivity and long cycle life, retaining 75% of capacity after 1,500 cycles.
