Perovskite Solar Cell with Over 27% Conversion Efficiency Developed

Researchers from the Institute of Semiconductors, Chinese Academy of Sciences, have developed a prototype perovskite solar cell with a photovoltaic conversion efficiency of 27.2 percent and significantly enhanced its operational stability. Regarding stability, the cell maintained 86.3 percent of its initial efficiency after continuous operation for 1,529 hours. The research findings were published online in Science.

Breakthrough Made in Saline-Alkali Soil Technology

A plant-based nano-silica technology for saline-alkali soil improvement has successfully undergone field trials in Jinpu New Area in Dalian, Liaoning province in northeast China. It was used on medium-to-heavily saline coastal soils with pH 10.54 and a salt content exceeding 5 percent to achieve a major breakthrough from zero corn yield per mu to 603.1 kg per mu in the same year.

Quantum Computer Interconnection Reaches 2,000 Km

A research team from the Pritzker School of Molecular Engineering at the University of Chicago has theoretically extended the connection distance between quantum computers to 2,000 kilometers. Based on this advancement, the university's quantum computer can now establish connections with equipment located as far away as the outskirts of Salt Lake City, Utah. The team stated that the technology for building a global-scale quantum Internet is now truly "within reach" for the first time.

Lab System Grows Materials on Its Own

A U.S. research team has developed a self-driving lab system which can autonomously "grow" materials. It is capable of independently completing the entire material synthesis and optimization process without continuous human intervention. Integrating robotic automation with machine learning algorithms, the system autonomously determines subsequent experimental steps, achieving fully closed-loop operation from experiment execution and performance measurement to result analysis.
