Temperature characteristics of Manakov photovoltaic solitons in two-photon photovoltaic photorefractive crystal were investigated by numerical methods. The results show that the peak intensities and full width of half maximum (FWHM) of two components of the bright-bright, dark-dark and bright-dark Manakov photovoltaic solitons are related to temperature. When temperature of crystal increases, peak intensities of two components of the bright-bright Manakov photovoltaic soiltons decrease and the full width of half maximum of two components increase. The dark-dark and bright-dark Manakov photovoltaic solitons have the same temperature characteristics as the bright-bright Manakov photovoltaic solitons. Moreover, two components of the Manakov solitons evolve into stable solitary waves by overcoming the less perturbation in a certain range of temperature.
