Solar system : The performance of poly(3‐hexylthiophene)/C 60 polymer solar cells is improved after thermal post‐treatment due to the optimization of the morphology of the photoactive layer, which creates efficient pathways for electron transportation to the cathode through nanoscale C 60 crystals and their distribution in the layer. The photoactive layer evolves from a homogeneous composite film to one with nanoscale C 60 crystals within the film (see picture).
