Inkjet printing of functional organic materials as deposition method holds the advantage for high throughput and low-cost production of organic electronic devices on flexible substrates in the future such as organic field effect transistors (OFETs) or organic solar cells (OSCs) [1,2]. In this context a three-dimensional electrode structure on a flexible substrate can be used for special application such as high voltage supply [3]. Therefore we investigate the inkjet printing process on these micro- or nanostructured PMMA-foils. The printing process was especially influenced by the capillary forces of the electrode structures. Here we show our results of the inkjet printing of semiconducting layers consisting of poly(3-hexylthiophene) (P3HT) in these three-dimensional structures. The preparation was done under ambient conditions and resulted in smooth layers as analysed with atomic force microscopy (AFM) and transmission electron microscopy (TEM).
