Flexible organic electronics are one of the most sought-after devices in the field of photovoltaics, sensors, or smart wearables. Here, the structure of the organic-metal interface and its modification potential are of utmost interest for future large-scale production. This study focuses on two semiconducting Poly(3-hexylthiophene-2,5-diyl) diblock variants, whose sprayed and doped thin films show excellent potential as thermoelectric generators. Using AFM, ellipsometry, in situ GISAXS/GIWAXS, and NR measurements, the structural changes of the polymer-gold interfaces were tracked during thermal annealing.
