- Abstract:
- We illustrate the ink-jet printing of a thin-filmlibrary
of donor/acceptor systems useful in bulk heterojunction
solar cells and their characterization utilizing a UV-vis/fluorescence
plate reader and an optical profilometer. In addition,
themorphology of thefilms has beenexaminedbyatomic force
microscopy (AFM). The ink-jet processing technology allows
printing of arrays of different donor/acceptor compositions on
one substrate aswell as the subsequent fast optical screening of
the electron transfer processes. The investigated films consist
of blends of a poly(methyl methacrylate) polypyridyl ruthenium(
II) copolymer (RuPMMA) as electron donor material
(p-type) andC60 fullerene (PC60BM) aswell as heptyl viologen
(C7-V) derivatives as electron acceptor materials (n-type).
