Chinese scientists have reported a major advancement in boosting both the efficiency and stability of perovskite solar cells, a step researchers say could help move the promising technology closer to large-scale industrial use.

A team led by You Jingbi, a professor from the Chinese Academy of Sciences' Institute of Semiconductors, said it has identified an additive that can raise the power conversion efficiency of perovskite solar cells to 27.2 percent. The devices also kept 86.3 percent of their initial efficiency after running continuously for 1,529 hours, about 63 days, at the maximum power point under standard sunlight — a sign of improved durability. The findings were published recently in the journal Science.

Profits of key steel enterprises in the first three quarters of 2025 hit their highest level for the same period in the past four years, according to Jiang Wei, vice-chairman and secretary-general of the China Iron and Steel Association.

The surge was driven by the steel industry's efforts in production control, supply optimization, industrial upgrading and efficiency gains, Jiang said at the third Sustainable Mineral Supply Chain Ecosystem Developers' Conference in Shanghai on Thursday.

On October 30, 2025, China achieved a milestone in uncrewed aviation with the successful maiden flight of the Boying T1400 Tandem Rotor Unmanned Helicopter, developed by Harbin United Aircraft Technology. The aircraft, weighing 1,400 kg and boasting an 8-hour endurance, has already garnered global attention for its dual-engine redundancy, 6,500-meter operational ceiling, and 650 kg payload capacity—capabilities that position it as a game-changer in cargo transport, disaster response, and precision agriculture .
