Abstract
A condensing lens, compound-eye lens condenser, and compound-eye concentrating-type solar cell assembly. The condensing lens is a convex lens that can reflect mutually parallel incident lights (3) onto a receiving surface (4) on the outer side of the lens and thus form spots. If the vertical distance from the contact point of any incident lights (3) contacting the lens to a light axis (103) of the lens is x, the vertical distance between a projection point formed from the incident light (3) reflecting onto the receiving surface (4) and the center of the spot is m, the radius of the lens is a, and the radius of the spot is b, then the lens meets the following condition: x/m=a/b. The condensing lens has a high transmission rate, and the energy distribution of the spots is more even after condensing, the transmission rate is 90% to 93%, and the energy distribution curve of the spots transmitted through the condensing lens is similar to saddle-shaped.
