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...
The beam emitted by almost all laser systems follows the Angle pattern of Gaussian distribution. The Gaussian irradiance distribution means that irradiance has a smooth peak at the center point and slowly declines toward the edge. In theory, the irradiance level of a Gaussian distribution can never reach zero, which means that the distribution can expand indefinitely. This phenomenon in the laser ...
Recently, DIT, a well-known semiconductor and display equipment manufacturer in South Korea, announced that the company has signed an agreement worth 20.52 billion Korean won to supply wafer processing equipment to SK Hynix. After the announcement, DIT's stock price rose for five consecutive days, entering the 16000 Korean won range. Then on the 22nd, it rose 2580 Korean won from the previous day'...
Recently, Murata Machinery USA, a representative Japanese manufacturer of machinery and CNC machine tools, announced the launch of the latest cutting-edge punch and fiber laser integrated equipment - MF3048HL. This integrated machine combines the advantages of punch operation and laser cutting technology, eliminating the need for separate settings or material transfer between machines.Muratec's pu...
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...
