Novel n-dopants for OPV and OLED, subproject NDOT-OLED
OLED displays, which are already found in every second new smartphone, and organic solar films, which are developed and commercialized in Dresden, have in common that they are made up of layers of small organic molecules. To improve the performance efficiency and service life of the components, the principle of doping the organic layers is used. This is done by adding suitable chemical compounds, known as p- and n-dopants, which generate additional positive and negative charge carriers.
For organic electronics applications, high-performance n-dopants are crucial for minimizing voltage losses and increasing power efficiency. This project aims to develop and test new classes of substances that strike the difficult balance between high doping strength and stability in mass production in order to accelerate the spread of sustainable organic photovoltaics, organic sensors, and energy-efficient OLED displays.
Fraunhofer IPMS in the project
In the NDOT-OLED subproject, Fraunhofer IPMS is conducting application tests in OLED components and comparing the new doping technology on high-resolution microdisplays as a reference for displays with the highest requirements in terms of brightness, OLED voltage, and crosstalk. The goal is to improve OLED performance in terms of lower operating voltage, improved efficiency, and longer service life.
