Abstract: This invention provides a light-concentrating structure with photosensitivity enhancing effect, including the substrate, buried layer, first electrode layer, second electrode layer, dielectric layer and interconnection structure. The substrate is equipped with a housing space; the buried layer is arranged above the substrate with the housing space; the first electrode layer is arranged above the buried layer; the second electrode layer is arranged in the middle of the first electrode layer; the dielectric layer is arranged above the second electrode layer; the interconnection structure is arranged above the substrate and the first electrode layer surrounding the dielectric layer, which forms an opening and a light-concentrating recess groove.
