Beschreibungen/Notizen

• Photo‐active layers from non‐stabilized P3HT:ICBA nanoparticles enable the fabrication of inverted organic solar cells from eco‐friendly, alcoholic dispersions. Exhibiting power conversion efficiencies (PCEs) ≈4%, the devices are competitive to state‐of‐the‐art P3HT:ICBA solar cells from chlorinated solvents. Upon thermal annealing, the short circuit current density and consequently the PCE of the inverted solar cells improve radically due to a more intimate contact of the nanoparticles and hence an enhanced charge carrier extraction.
