Abstract [en]

Understanding and controlling crystallite formation and orientation in thin semiconducting polymer films is paramount to building more efficient organic electronic devices for renewable energies. Indeed, chain packing and crystallization in such films determines to a large extent their electronic and optical properties [1-6]. Surprinsingly, little work has been done on the influence of confinement in semiconducting films. In this talk, we present results on the effect of confinement under applied pressure in one of the highest performing and most widely used organic semiconductor: regio-regular poly-3-hexylthiophene (rr-P3HT) thin films. We studied films with thickness ranging from ≈15-100 nm, and processed in various conditions of annealing and nano-confinement. Using X-ray diffraction techniques, atomic force microscopy (AFM) and UV vis spectroscopy we show that crystalline orientation, crystal density, kinetics and optical absorbance are affected by confinement. We expect these findings to help better understand the role of confinement on crytallization in semiconducting films, and to have strong implications for organic electronic applications and photovoltaics.
