Paper Abstract

In photorefractive composites, we replace the commonly used fullerene derivative phenyl-C61-butyric acid methyl ester (PCBM) by the perylene bisimide dimer DiPBI. In samples, wherein poly-n-vinylcarbazole (PVK) is the charge transporting agent and 4-cyano-4-n-pentylbiphenyl (5CB) the nonlinear optical unit, we observe dramatic enhancements in the overall performance of the composites. When we replace PVK by N,N-diphenyl-N, N-bis(3-methylphenyl)-[1, 1-biphenyl]-4, 4-diamine (TPD) doped polystyrene (PS), the internal photocurrent efficiency is further improved by a factor 11.
