Abstract: A solar reflective condensing device, including a condensing film (2), a face-contour bottom plate (3), and a face-contour focusing support (4). The condensing film (2) is arranged on a top surface of the face-contour bottom plate (3). The face-contour bottom plate (3) is a thin plate, a bottom surface of which is attached to a top surface of the face-contour focusing support (4), and reproduces the shape of the top surface of the face-contour focusing support (4). The face-contour focusing support (4) includes a top optical surface (4a) and a focusing structure (4b) integrated with the face-contour focusing support. The top optical surface (4a) is positioned on the top surface of the face-contour focusing support (4), and a central point of the focusing structure (4b) integrated with the face-contour focusing support is positioned at a focus (f) of the top optical surface (4a).
