Tapered concentrator used for CPV and design method therefor

The invention discloses a tapered concentrator used for CPV and a design method therefor. All incident light passing through a Fresnel lens is focused and then is input to an optical fiber, so that the high-strength sunlight focused by multiple optical units can be guided to a piece of photoelectric conversion material through the optical fiber to be subjected to photoelectric conversion; therefore, the number of the photoelectric conversion units is reduced, the installation and maintenance are facilitated, and the cost is lowered; the parameters of the tapered concentrator have the following characteristics: formulas are as shown in the specifications, wherein alpha is the output end horizontal inclined angle of the tapered concentrator, L is the length of the tapered concentrator, and 2A is the diameter of the input end of the tapered concentrator. 本发明公开的种用于CPV的锥形聚光器及其设计方法，可以将经菲涅耳透镜所有入射光线汇聚后全部输入至光纤，这样可以实现数个光学单元所汇聚的高强度太阳光通过光纤引导在片光电转换材料上，进行光电转化，这样减少了光电转化单元，利于安装维护，降低了成本。所述锥形聚光器的参数具有以下特征：其中，α为锥形聚光器的输出端水平倾斜角，L为
