The invention provides a solar curtain which comprises a curtain body. The curtain body comprises an electric heating layer, a photoelectric conversion layer which is used for providing heat for the electric heating layer, and an insulating protective layer. The photoelectric conversion layer comprises a flexible thin film solar battery and a battery connected with the flexible thin film solar battery. The flexible thin film solar battery is arranged on the sunlight incidence side of the electric heating layer. The electric heating layer is wrapped by the insulating protective layer. According to the solar curtain, solar and electric energy is used to heat indoor temperature, which can greatly save non renewable energy and effectively use solar energy; and the solar curtain has the advantages of fast heating speed and uniform heating, has a far infrared function, and is suitable for wide-range promotion and use.
