Scientists from Kiel University (CAU) have investigated the possibility of using organic optoelectronics in the field of measurement technology. The goal is to integrate OLEDs and OPVs on a chip for the development of future lab-on-chip system for fluorescence detection. In a first proof-of-principle experiment, organic light-emitting diodes and organic solar cells in various designs were realized on a substrate in the clean room of the Kieler Nanolabor and initial fluorescence measurements were carried out. These results were presented in a lecture at the XXXI. Messtechnisches Symposium des Arbeitskreises der Hochschullehrer für Messtechnik (S. Jahns, J. Balke, A.F. Iwers, M. Gerken: Organic optoelectronics for lab-on-chip fluorescence detection, Proceedings AHMT 2017).
By introducing nano- and microstructures into organic solar cells (OPV) and organic light-emitting diodes (OLED), CAU scientists want to specifically influence the properties of the components. For this purpose, a simulation model was implemented with which the influence of grid structures on the emission characteristic of an OLED can be investigated. In a first study it was investigated both theoretically and experimentally, how the structures of the grid, absorption effects within the nanostructured OLED and the layer thickness of the cathode affect the light extraction. The results were presented in an abstract at the conference International Conference on Electromagnetics in Advanced Applications 2017 (H. Lüder, M. Bremer, M. Gerken, Simulation of nanostructured emission layers for tailoring the angular radiation pattern of OLEDs, Proceedings ICEAA 2017).
