On the Influence of Low Magnetic-Fields on the Photocurrent of Conjugated Polymers

The influence of low magnetic fields on the yield of photogenerated charge carriers in conjugated polymers was calculated by means of a phenomenological quantum mechanical model. The problem was solved both by using the perturbation approach and numerically. The results of the calculations were compared with measurements of PPV and its phenyl-substituted derivatives PPPV and DMOP-PPV. Informations about the different rate constants could be gained.
