The laser pulse can make good contact with the silicon surface
Draining current from the wafer requires many small holes in the non-conductive layer to allow the metal electrode to contact the silicon wafer. The LFC process enables nearly 100,000 contact points on the wafer to establish a connection with a single laser pointer pulse. The biggest difficulty of this work is that the laser pulse can form…
New laser pointer manufacturing process revolutionizes the photovoltaic market
The Solar Energy System Research Institute in Freiburg, Germany has developed a laser pointer-based manufacturing process method that is revolutionizing the photovoltaic market. Mass production of point-contact solar cells was realized for the first time. Millions of batteries with high efficiency levels have entered the market. In the next few decades, one of the main challenges…
Combination of standard laser pointer dyes
In recent years, when the graphene industry is booming, another new type of single-element two-dimensional atomic crystal material-black phosphorus has been discovered. Similar to graphene, black phosphorus has many excellent properties, so it is called a “dream material” comparable to graphene. Its nonlinear optical characteristics have been confirmed by many domestic and foreign companies and…
Different types of lasers are built on silicon materials
Building a quantum cascade laser on silicon is extremely challenging, mainly due to the strong absorption of SiO2 in the long-wavelength mid-infrared band. “This means that we not only need to build different types of laser pointer on silicon materials, but also different types of silicon waveguides.” The project leader said: “We built SONOI waveguides and used…
