The invention provides a sun-shading device. The sun-shading device comprises a frame, wiring terminals, an electric energy transformer and m*n sun-shading panels, wherein the sun-shading panels in aclosed state cover a mounting face inside the frame; and the sun-shading panels in an opened state can rotate by 0-180 degrees relative to the mounting face inside the frame. The sun-shading device can adjust the angle of the sun-shading panels receiving sunlight within different time periods in the daytime so as to collect optical energy at high efficiency and convert the optical energy into electric energy to be supplied to backward-stage equipment. Meanwhile, the sun-shading device can conduct sun-shading, or ventilating or light transmitting. Furthermore, the invention further provides a building. The building comprises walls, a plurality of glass window and a plurality of sun-shading devices. The sun-shading device is relatively simple in structure, convenient to produce and install and capable of creating a
