Abstract
We have developed a model of current-voltage (I-V) characteristic for an ITO/PEDOT:PSS/MEH-PPV/Al photodetector. The model is based on the solution of the continuity and drift-diffusion equation for hole polarons. Detailed analysis of the generation process is carried out through the investigation of the internal quantum efficiency (QE) dependence on incident photon flux density, incident light wavelength, and applied electric field. An excellent agreement between the simulated and measured I-V characteristics has been achieved in the maximum external QE wavelength range of the photodetector for a wide range of bias voltages from 0 to -8 V.
