Abstract :
The interpenetrating network morphology of the organic solar cells was investigated using a blend of P3HT:PC[70]BM at ratio of 1:0.84 wt%. To analyze the dependence of organic solar cell efficiency on the morphology of the composite was used atomic force microscopy (AFM) and transmission electron microscopy (TEM). It is experimentally identified the phase-separated domain size that is formed and distributed for the two organic semiconductor materials at the cross section of the active layer.
