The present invention discloses a low magnification and high magnification light-concentration solar cell. The solar cell comprises a box body and a containing slot arranged in the box body, wherein the opening of the containing slot is upward. The insides of the left inner wall and the right inner wall of the containing slot are interlinked, and the containing slot is provided with a first slide-guiding chute. The bottom of the containing slot is provided with a first cavity. The containing slot is slidably connected with a first slide-guiding block, wherein the containing slot is matched with the first slide-guiding block. The first slide-guiding chute is slidably connected with a second slide-guiding block, wherein the first slide-guiding chute is matched with the second slide-guiding block. The end face, near the first slide-guiding block, of the second slide-guiding block is fixedly connected with the corresponding end face of the first slide-guiding block. The second slide-guiding block is threadedly connected with a lifting threaded rod, wherein the lifting threaded rod extends up and down, and the second slide-guiding block is matched with lifting threaded rod. The bottom of the lifting threaded rod stretches into the first cavity, and the bottom of the lifting threaded rod is provided with a first belt wheel. The top of the lifting threaded rod stretches out of the topend face of the box body, and the top of the lifting threaded rod is provided with a second gear. The solar cell has the advantages of simple structure, stable regulation, good light-concentration effect, high energy conversion efficiency, stable magnification regulation and relatively-high practical performance.
