【Abstract】 In this paper, the law and design theory of three-dimensional(3-D) two-stage solar collector is introduced, it also sums up the development process and present situation of various parts made up the system. The total geometric solar radiation concentration of an ideal 3-D two-stage concentrator is accurately expressed in an explicit way. The analysis and discussion have been made for its research and application with 3-D two-stage solar collector in future.更多还原
