Abstract
The bulk photovoltaic effect in non-centrosymmetric crystals is caused by asymmetric generation, recombination or scattering of excited non-equilibrium electronic carriers. Photovoltaic effects in (Pb,La)(Zr,Ti)O3-based ceramics have been investigated using linearly polarized light. Angular dependence of the photovoltaic voltage and current on the polarization direction of the light was observed in doped (Pb, La)(Zr,Ti)O3 ceramics. A phenomenological model was proposed to fit the experimental results from which the photovoltaic coefficients were calculated.
