Recently, Longi Green Energy Technology Co., Ltd. (hereinafter referred to as "Longi"), as the first unit, published a research paper titled "Silicon heterojunction back contact solar cells by laser patterning" online in the journal Nature, reporting for the first time the research results of breaking through 27% of the photoelectric conversion efficiency of crystalline silicon cells through full ...
According to relevant media reports, a research team from the Helmholtz Center in Berlin, Germany, and Humboldt University has jointly developed a new type of perovskite stacked battery. This battery has broken the world record for similar batteries with a photoelectric conversion efficiency of 24.6%. In the solar cell family, in addition to silicon-based solar cells, there are also thin-film so...
Recently, the Jiang Haihe Research Group of the Health Institute of the Chinese Academy of Sciences Hefei Institute of Materia Medica made important progress in the research of the high-energy pulsed laser transmission system in the mid infrared band, and designed a 78 μ The 6-hole microstructure anti resonant hollow core fiber (AR-HCF) with a larger core diameter achieved efficient transmissio...
At present, the navigation system has become an important equipment on ships, aircraft, missiles, automobiles and other navigational vehicles. Laser Doppler radar has become an important development direction in the field of velocity measurement technology because of its high accuracy, good spatial resolution and fast dynamic response. The application of the three-beam Doppler Lidar in the...
The team from the Photonic Systems Laboratory at the Federal Institute of Technology in Lausanne has developed a chip level laser source that can improve the performance of semiconductor lasers while generating shorter wavelengths.This groundbreaking work, led by Professor Camille Br è s and postdoctoral researcher Marco Clementi from the Federal Institute of Technology in Lausanne, represe...
