The bulk photovoltaic effect in non-centrosymmetric crystals is caused by asymmetric generation, recombination or scattering of excited nonequilibrium electronic carriers. In this paper, the photovoltaic effect has been investigated in relaxor ferroelectric Pb(Zni/3Nb2/3)C>3 single crystals using linearly polarized light. Angular dependence of photovoltaic voltage and current on the polarization direction of light was observed in the crystal. A phenomenological model was proposed to fit the experimental results from which the photovoltaic coefficients were calculated.
