In order to explore the influence of battery position and angle on the uniformity of battery surface energy density and light receiving rate in the reflective highpower condensing system， a reflective highpower concentrating system was designed and built. The optical path of the reflective highpower condensing system was optimized through the combination of experimental research and TracePro ray tracing. The surface energy density of the battery was numerically calculated by using the TracePro software. The research results show that when the cell is in the coordinate values of 0,-2 and 52 and forms a 45° angle with the focal plane,the light receiving rate on the cell surface is 56.63%,the uniformity of the light spot on the cell surface is 72.85%,the distribution of surface energy density and energy receiving rate are optimal by comprehensive comparison,and the photoelectric conversion efficiency is the highest.
