According to the present invention, driving energy of a blind is obtained by self-generation. Since operation of the blind is performed by electric control, any separate wiring is not required outside the blind. Accordingly, plastering of the present invention is aesthetically improved. In addition, since heat insulation property and durability are improved, an indoor temperature can stably be maintained regardless of outdoor temperature. In order to achieve the purposes, a window with a built-in blind, comprises: an external window and an internal window which are spaced apart from each other and fixed to a frame-shaped fixing frame; a blind unit including a motor between the external window and the internal window to be operated by receiving power, and a plurality of blades which can be folded or unfolded with respect to each other and whose angle of gradient is adjusted by rotary power of the motor; and a power generating unit which generates power using sunlight via solar cell modules arranged on surfaces of the blades. The external window, which comes in contact with the outside, is made of a tempered glass on which a material for blocking a certain wavelength is coated. The internal window, which comes in contact with the inside, consists of a double glass panel composed of an internal glass plate and an external glass plate which are fixed to both sides of a frame-shaped lattice having a through hole inside the lattice and form hollow parts inside the internal and external glass plates. |
