FIG. 1.

DSC thermogram of the P3HT powder used in this work. The inset box shows the onset on an expanded scale. Also shown (inset) are the chemical structures of P3HT (a) and PCBM (b), the organic solar cell structure (c), and the expected energy band diagram (d). Here, and denote the PEDOT:PSS layer and the blend film of P3HT and PCBM, respectively.
