Energy-saving solar cells can be printed out like newspapers

Energy-saving environmentally friendly solar cells can be printed like a newspaper, artificial muscles can be self-healing telescopic freely. Yesterday, the symposium on "Natural Flexible Electronics" organized by Nature Science and Nature Communications Magazine jointly with Nanjing University of Technology - Opportunities and Challenges and the International Symposium on "Optoelectronics, Materials and Energy" were held in Ningxia Internationally renowned experts revealed their latest research results.

Australian Academy of Engineering, Monash University, Australia, Department of Materials Engineering Professor Cheng Yibing is an internationally renowned expert in the field of inorganic non-metallic materials, his main research direction is the use of printing methods to manufacture solar cells. "At present, in my laboratory, solar cells have been made using printing technology." He introduced that a 30 cm x 30 cm solar cell was manufactured in about 1 minute, and the conversion rate of the cell to solar energy had reached Up 22%, close to the market silicon cell conversion efficiency.

Bao Zhenan, a member of the American Academy of Engineering, who was born in Nanjing in 1970 and named one of the top 10 scientific figures in the world last year, revealed that her team made another breakthrough in elastic fiber research this year. Bao Zhendong committed to artificial skin research, this simulation of human skin soft plastic electronic sensor device - artificial electronic skin, is expected to prostheses, robots, mobile phones and computers touch screen, automotive safety and medical devices and many other aspects of a wide range application.

In October last year, Bao Zhenan team published a paper in Science magazine, they developed a man-made skin as thin as paper, with a double structure, the outer is a sensor of perceived stress, made of plastic and carbon nanotubes, the inner layer is flexible Electronic circuits, which convert stress signals into electrical signals, transmit them to the brain, stimulate neurons, sense that they can sense butterflies and flies that fall on the surface and react. This year, her team made another breakthrough in the study of elastic fibers. The developed artificial muscle not only has the full flexibility but also has a strong ability of self-repairing, which can be used to manufacture pressure-sensing devices. In the future, it can be difficult to repair the detectors Fighting in space exploration.

According to reports, the conference attracted more than 200 experts and scholars from more than 10 countries and regions attended the meeting, holding nearly 40 special reports.
