The photo-thermal double-response intelligent window comprises three window panels (1) arranged at intervals, a first hydrogel layer (2) and a second hydrogel layer (3), wherein the first hydrogel layer (2) and the second hydrogel layer (3) are clamped between every two adjacent window panels, and the peripheries of the window panels are sealed. The first hydrogel layer is thermo-sensitive amide hydrogel, the second hydrogel layer is solid hydrogel added and uniformly dispersed with light-absorbing nanoparticles or light-absorbing dye, and the window panel is transparent glass or plastic through which sunlight can pass. The response speed and the photothermal conversion capacity under sunlight stimulation are accelerated through the arranged second hydrogel layer, so that thermochromism of thermosensitive amide hydrogel in the first hydrogel layer is accelerated, the photothermal and thermochromism dual response speed is high, the first hydrogel layer and the second hydrogel layer respond to each other to ach
