    Donor-acceptor heterojunction solar cells based on perylene dimide and perylene bisbenzimidazole
    (Cambridge Univ Press, 2006) Erten, S.; Meghdadi, F.; Gunes, S.; Koeppe, R.; Sariciftci, N. S.; Icli, S.
    We have fabricated heterojunction solar cells comprising active layers of perylene diimide (PDI) or perylene bisbenzimidazole (CONPER, conjugated perylene dye) as electron acceptor and ZnPC as donor. Bilayer solar cells were produced by successive evaporation of zinc phthalocyanine (ZnPC) and perylene diimide (PDI) or perylene bisbenzimidazole (CONPER) on glass substrates coated with indium doped tin oxide. Active layers with different thickness were evaporated. The bilayer cells were characterized under simulated AM 1.5 illumination (100 mW/cm(2)). The best results were obtained for the device structure of ITO/PEDOT/ZnPC (40 nm)/perylene bisbenzimidazole (60 nm)/Al (70 nm).

    Soluble derivatives of perylene and naphthalene diimide for n-channel organic field-effect transistors
    (Elsevier Science Bv, 2006) Singh, Th. B.; Erten, S.; Guenes, S.; Zafer, C.; Turkmen, G.; Kuban, B.; Teoman, Y.; Sariciftci, N. S.; Icli, S.
    Solution-processed n-type organic field-effect transistors (OFETs) have been fabricated using soluble derivatives of perylene diimide and naphthalene diimide. We report the synthesis of the organic semiconductors and the fabrication of bottom gate OFET devices using solution-processed organic dielectrics. Surface morphology studies reveal films with layered textures and liquid crystalline-like structure. Devices show field-effect electron mobilities of 10(-2) cm(2)/V s and 10(-3) cm(2)/V s for N,N'-bis-n-butyl-1,4,5,8-naphthalenediimide-NDI under inert conditions and in air, respectively. N,N'-bis-(1-pentyl)hexyl-3,4,9,10-perylene diimide-PDI-4 shows mobility of 5 x 10(-4) cm(2)/V s. Organic field-effect transistors based on N,N'-bis(dehydroabietyl)-3,4,9,10-perylene diimide-PDI-1 derivative exhibit ambipolar transport. (c) 2006 Elsevier B.V. All rights reserved.
