Abstract: The first comparison of the structure and electrical conductivity properties of spin cast (SC) and Langmuir-Schaeffer (LS) films of regioregular poly(3-hexylthiophene) (P3HT) is presented. Results show that, while the inclusion of Au nanoparticles (NPs) caused the lateral conductivity to decrease in SC films, in LS films the lateral conductivity increased by a factor of 2.
