The Photonics area is part of the Functional Printing & Embedded Devices Department and specialises in printed optoelectronic device research and development. Optoelectronic devices work because of the interaction between light and electricity. Specifically, we work on the following technologies:
Solar cells (OPV), which transform sunlight into electricity. The diodes are made up of multiple layers of organic and inorganic materials.
Inorganic light-emitting diodes (EL), which transform electricity into light. This is another multi-layer system made up of inorganic materials prepared through various printing techniques, such as serigraphy or inkjet printing. The light surface is flat and may be flexible.
Hybrid light-emitting diodes (HyLED), which transform electricity into light. This is an innovative type of device that combines organic light-emitting layers with inorganic layers to transport the charge, thus combining the versatility of the organic component with the stability in air offered by the inorganic layers. The light surface is flat and may be flexible. The diodes work on 3 V and continuous current.
