In order to obtain the effect of temperature on the interactions of screening-photovoltaic bright spatial solitons in two-photon photovoltaic photorefractive media, taking the two mutually coherent optical beam as the input wave, the beam propagation equation is solved numerically under different temperatures. The result shows that the interaction of two in-phase solitons still has fusions along with temperature varying in the room temperature range. With the raising of the temperature of media to 350 K, two in-phase solitons fuse a solitary wave. With the varying of the temperature, the repulsions of two out-of-phase solitons are increasing. The repulsions and the energy transferring increase with the varying of the temperature for the -phase-difference solitons. Two solitons crash in the interactions process when the varying is great enough.
