Abstract Time-dependent measurements of both power conversion efficiency and ultraviolet-visible absorption spectroscopy have been observed for solar cell blends containing the polymer poly(3-hexylthiophene-2,5-diyl) (P3HT) with two different functionalized C 60 electron acceptor molecules: commercially available [6,6]-phenyl C 61 butyric acid methyl ester (PCBM) or [6,6]-phenyl C 61 butyric acid octadecyl ester (PCBOD) produced in this laboratory. Efficiency was found to decay with an…

TLDR
These methods have been very effective to give nanoscale phase-separated morphology in the horizontal direction (parallel to the fi lm surface), however, the methods have limited control over the vertical distribution of the components in active layer, although the Vertical distribution is very critical for effective transport of charge carriers.
