A team of scientists at the Technical University of Denmark has created a selene-based solar cell by replacing thermal annealing with a new laser annealing strategy."In our work, we investigated the potential of this laser annealing strategy specifically for selenium thin film solar cells, and we report a new world record for fill factor, a new world record for ideal factor, and the most advanced ...
Scientists from Leibniz University in Hanover have pioneered the development of a new manufacturing technology - UV LED based microscopy projection lithography. This technology is expected to completely change the manufacturing method of optical components, providing high resolution at lower cost and ease of use. The MPP system utilizes the power of UV LED light sources to transcribe the structura...
Light can calculate functions during propagation and interaction with structured materials, with fast speed and low energy consumption. The use of all optical neural networks for general computing requires an optical activation layer with nonlinear dependence on the input. However, existing optical nonlinear materials either have slow speeds or very weak nonlinearity at the level of natural light ...
Plasmology plays a crucial role in advancing nanophotonics, as plasma structures exhibit a wide range of physical properties that benefit from local and enhanced light matter interactions. These characteristics are utilized in many applications, such as surface enhanced Raman scattering spectroscopy, sensors, and nanolasers.In addition to these applications, the ultrafast optical response of plasm...
Scientists are exploring new ways to get around limitations on the lithography machines used to produce microchips. Researchers are using particle accelerators to create new laser sources that could lay the foundation for the future of semiconductor manufacturing.Plans are underway to build a particle accelerator with a circumference between 100 and 150 meters (328 and 492 feet), about the size of...
