SpletUltra-thin (<10 nm thick) blend films had greater P3HT order than the bulk and reorganised at lower temperatures, which we propose is due to a P3HT-rich interfacial layer at the film/air interface, and that extra disordered component retained despite annealing is due to P3HT trapped in a disordered state within the corresponding PCBM-rich ... SpletPCBM was spin-coated onto the ITO/ZnO substrates at 600 rpm for 60 s, resulting 28 nm thick film. The substrates were thermally annealed at 150 °C for 5 min inside a N2-filled glove box to introducing crystallization of PCBM. 10 mg/mL P3HT solution in chlorobenzene was spin-coated at 1000 rpm for 60 s, and resulting 47 nm P3HT film
