摘要	In order to meet the concentrative requirements of concentration photovoltaics system (CPVs) and resolve the traditional point focus concentrator's problems, including non-uniform irradiance, large aspect ratio and low concentration, a novel concentrator with small aspect ratio, uniform irradiance and high concentration is presented in this paper based on the precondition that no additional secondary optical element is increased. According to the theories of Kohler illuminating, constant optical path length, and Snell's law in geometric optics, we obtain the profiles of concentrator's surface through numerical solution of the constant optical path length equations. Using the optical software TracePro, we trace and simulate the CPVs. The results show that the maximum irradiance value of focal spots on the surface of solar cell is only 2300 times of the sun for the 725 concentration ratio, which is about 1/10 of the case of point focus concentrator. The aspect ratio of system is 0.3, and the acceptant angle is 0.72. The design realizes the objectives of compact structure and high concentrative performances, which provides an effective way for realizing the high concentration CPVs' miniaturization and simplification.
