Aalto-China collaboration resulted in a novel 2-stage dish solar concentrator
Here we propose a novel 2-stage dish concentrator system for concentrating solar power plants based on the so-called overlap method, which improves both the radial flux concentration ratio (b) and the intercept factor (g) of the concentrator. The 2-stage dish is composed of paraboloid primary and hyperboloid secondary mirrors having a special hollow structure enabling the mirrors to overlap, but avoiding excess shading. Geometric and optical analyses with ray-tracing show maximum values ofconcentration ratio15,498 and intercept factor 0.78. Also, the size of the focal spot could be reduced. The concept is applicable for solar tower concepts enabling more compact unit mirrors and reducing the receiver size. The results were recently presented in a journal article: Jun Wang , Song Yang , Chuan Jiang , Qianwen Yan , Peter D.
