We present a theoretical analysis of temperature effects on the self-deflection of photorefractive solitons in biased photovoltaic-photorefractive materials. The bending distance of the bright solitary beam center increases and, reaches its maximum value at a character temperature and then decreases as temperature rises and, approaches zero at low and high temperatures. Both the maximum value and character temperature increase with the input power density. The dark irradiance dominates the temperature dependence of bending distance in most values of temperature besides in higher temperature range in which the diffusion process will dominate.
