The bulk heterojunction (BHJ) polymer photovoltaic (PV) cells using a composite of (P3HT) and (PCBM) shows a better performance among the Organic Solar Cells and this has been the most studied and successful system [4,5]. The device morphology has been shown to be a critical parameter governing charge transport properties of polymer bulk heterojunction (BHJ) solar cells. In this AFAM, Atomic Force Spectroscopy and Nanoindentation were used to study the effect of the fullerene presence and the annealing on the P3HT:PCBM nanomechanical behavior. The P3HT:PCBM thin films were prepared by spin coating on glass substrates and then annealed at 100 °C and 145 °C for 30 min. Large phase separation was identified by optical and Atomic Force Microscopy (AFM) for the annealed samples. These results revealed the effects of Thermal annealing on the device morphology and its performance and efficiency.
