Title: Photoconductivity in molecularly doped poly (methylmethacrylate) sandwich cells
Authors: Rani, Joseph
Keywords: Poly(methyl)methacrylate
sandwich cells
photocurrent technique
Issue Date: 13-Jan-2007
Publisher: American Institute of Physics
Abstract: Poly(methyl)methacrylate was made photoconducting by molecular doping and the photoconductivity was investigated using modulated photocurrent technique . Low-temperature current-voltage measurements showed that the transport mechanism was thermally activated hopping. An experimental investigation of the photoconductivity action spectrum along with theoretical calculation enabled an estimation of the diffusion coefficient of the material. The presence of states with a distribution of lifetimes could be understood from the frequency response of the photocurrent . The photocurrent was due to the field-assisted dissociation of these states
