We show that self-coupled and cross-coupled vector beam evolution equations in properly oriented biased photorefractive-photovoltaic crystals can exhibit bright-bright and dark-dark soliton pair solutions under steady-state conditions. When the bulk photovoltaic effect is neglectable under short-circuit conditions, these vector solitons are self-coupled and cross-coupled vector solitons for screening solitons. When the external field is absent, these vector solitons predict self-coupled and cross-coupled vector solitons for photovoltaic solitons in open- and closed-circuit photorefractive-photovoltaic crystals. The stability properties of these vector pairs are also discussed in detail.
