Transparent, conductive films promising for developing flexible screens

ScienceDaily.com: Nanotechnology News - 7 июня, 2018 - 00:02
Because silver is less brittle and more chemically resistant than materials currently used to make these electrodes, the new films could offer a high-performance and long-lasting option for use with flexible screens and electronics. The silver-based films could also enable flexible solar cells for installation on windows, roofs and even personal devices.
