According to foreign media reports, the University of New South Wales researcher Piria recently invented a method to improve the efficiency of thin-film solar panels. The current thin film solar panel efficiency is 8--10%, and her method can be increased to 13-15%. The ray tracing ability is over 50%. The Intergovernmental Panel on Climate Change (IPCC) reported in Bangkok on May 4 that fighting global warming will not affect economic growth, but will find a weapon for the world. |
As a filler metal welding wire or both as a conductive wire welding materials used. When gas welding and gas tungsten arc welding, welding filler metals used; in submerged arc welding, electroslag welding and other time MIG arc welding, welding filler metals both, but also conductive electrodes. Surface oxidation coated wire is not the role of flux.
