Abstract: An investigation into the influence of annealing time on structural ordering of Poly-3-Hexylthiophene has been performed via analyses of absorbance data on the premise that ordering status is reflected on the optoelectronic properties. Thin films heated from 0 to 100 minutes were examined. It was found that 20 minutes annealing yields a thin film with highest structural ordering, with density of states of 5.76×1038 m-3 kg-1 and carrier density of 5.24×108 m-3. Samples annealed beyond 40 minutes exhibited a balanced presence of ordered and disordered phases. The results demonstrated that during thermal treatment at a fixed temperature, the structural ordering and conformity continuously change with time, affecting the optoelectronic properties; thus, emphasizing the necessity of “time-profile” to determine the appropriate annealing time for a specific application of the polymer.
