Flexible, transparent electronics are getting closer to becoming a reality with the development of robust alternatives to indium-based electrodes. EU-funded researchers have created thin films that could revolutionise solar panels, light-emitting diode (LED) lighting and touch screens.
Indium-based materials form the essential element in virtually all current-generation flat-panel displays, high-efficiency solar cells, and are part of organic and inorganic LEDs. However, indium is increasingly rare and expensive.
