Researchers at Ruhr-Universität Bochum and the University of Wuppertal in Germany have come up with a new fabrication process for transparent ultra-thin silver films. The new process produces a material capable of increasing the efficiency of solar cells and light-emitting diodes. Up till now, traditional chemical methods have not been able to produce ultra-thin and pure silver films, the scientists say in a research paper published in the journal Angewandte Chemie. This is because precursors for the fabrication of ultra-thin silver films are highly sensitive to air and light. They can be stabilised with fluorine, p ... (full story)
