Deformation. In this way, when the solar wafer stack 10 is disposed on the structural reinforcing bottom plate 11, when the structural reinforcing bottom plate 11 is subjected to gravity or external force, the gravity is transmitted to the periphery, and the structural reinforcing base plate 11 provides good mechanical structure. The intensity, therefore, can evenly cancel the gravity, maintaining the relative distance between the concentrating mirror 16 of the solar wafer set 10 and the solar wafer 14 and the center position of the focused spot of the concentrating mirror 16 without affecting its performance. In addition, since the structural reinforcing base plate 11 is less prone to deformation, the working distance of the solar cell 1 is not affected, so that no error occurs, making the assembly work smoother and more convenient. In summary, the structural reinforcement substrate of the present invention and the solar cell system to which it is applied include a plurality of lateral groove structures, each of which has a slope on both sides thereof and a curved bottom surface thereof to provide mechanical strength. Therefore, it is less prone to warp deformation when subjected to gravity or external force, and can maintain the flatness of the receiver of the solar cell, maintain the relative distance between the concentrating mirror and the solar wafer of the solar crystal chip group, and focus the condensing lens _ The center of the point does not affect its performance.
