The evolution of morphology in poly(3-hexylthiophene) (P3HT):[6,6]-phenyl C61-butyric acid methyl ester (PCBM) bulk-heterojunction solar cells during thermal annealing is studied by in situ grazing incidence X-ray diffraction, ellipsometry, and field-effect-transistor measurements. We conclude that the solar-cell performance initially improves thanks to the crystallization of the polymer chains, and then to the diffusion and aggregation of fullerene molecules.
