The invention relates to a corrugated folding energy-saving safety window, which comprises a corrugated folding window frame, a glass component, a flame-retardant fiber fabric, a flexible photovoltaicmodule and a vanadium dioxide low-temperature phase-change film. When the window is opened, the window is corrugated; meanwhile, the flexible photovoltaic module can fully absorb solar power after the module is unfolded; the vanadium dioxide low-temperature phase-change film on the glass window undergoes a phase change when the outdoor temperature reaches the temperature near the film phase change; and the phase-change film converts into an opaque film to reduce light incidence and indoor temperature. When a fire or explosion hazard occurs in the room, a user can open the glass window and quickly jump to a place between the glass window and the first fan photovoltaic window. The space is open at the top and the bottom is a folding steel frame, at the same time, the flame-retardant fiber fabric is pulled to protect the user. The safety window has the advantages of diversified functions, and the flexible photovoltaic module is used to directly convert solar radiation into electric energy to generate electricity, so that buildings energy conservation is promoted and security for emergencies is provided.
