Here we present studies on bilayer devices using organic electron acceptors with varying LUMO levels and M3EH-PPV. It is found that the open-circuit voltage scales linearly with the LUMO level of the acceptor, reaching values as high as 1.5 V when cyano-substituted poly(p-phenyleneethynylene)-alt- poly(p-phenylenevinylene) copolymers are used. Further, we discovered that for an increasing number of triple bonds in the repeat unit of the acceptor polymer the device performance decreases with increasing thickness of the acceptor layer. Also, the quantum efficiency was smaller when using polymers with higher LUMO levels. Thus, further effort is needed to design optimum acceptor polymers for devices exhibiting large open-circuit voltage and high quantum efficiency}, language = {en} } @article{DaeublerPfeifferHoerholdetal.1999, author = {D{\"a}ubler, Thomas Karl and Pfeiffer, S. and H{\"o}rhold, Hans-Heinrich and Neher, Dieter}, title = {Photogeneration of charge carriers in segmented arylamino-PPV derivatives}, year = {1999}, language = {en} } @article{DaeublerNeherRostetal.1999, author = {D{\"a}ubler, Thomas Karl and Neher, Dieter and Rost, H. and H{\"o}rhold, Hans-Heinrich}, title = {Efficient bulk photogeneration of charge carriers in arylamino-PPV polymer sandwich cells}, year = {1999}, language = {en} } @article{DaeublerGlowackiScherfetal.1999, author = {D{\"a}ubler, Thomas Karl and Glowacki, Ireneusz and Scherf, Ullrich and Ulanski, J. and H{\"o}rhold, Hans-Heinrich and Neher, Dieter}, title = {Photogeneration and transport of charge carriers in hybrid materials of conjugated polymers and dye-sensitized TiO2}, year = {1999}, language = {en} } @article{DaeublerCimrovaPfeifferetal.1999, author = {D{\"a}ubler, Thomas Karl and Cimrova, V. and Pfeiffer, S. and H{\"o}rhold, Hans-Heinrich and Neher, Dieter}, title = {Field and wavelength dependence of charge carrier photogeneration in soluble PPV derivatives}, year = {1999}, language = {en} }
