Morphology, charge transport properties, and molecular doping of thiophene-based organic semiconducting thin films
… properties can be intentionally modified by doping these layers with a strong electron acceptor. By means of optical spectroscopy, the layer morphologies of poly(3-hexylthiophene), P3HT, P3HT-fullerene bulk heterojunction blends, and oligomeric polyquaterthiophene, oligo-PQT-12, are studied …

Device Physics of Organic-Inorganic Hybrid Perovskite Semiconductors
… Finally, the dissertation explores the doping of metal halide perovskites as a means to control charge carrier concentration. An additive-assisted strategy is developed for n-type molecular doping of organic-inorganic hybrid perovskite (OIHP) MAPbI₃, with a specific focus on the effects …
