Problems solved by technology
[0007] Among the various existing schemes, the non-concentrating collection method has the defects of high power loss and the need for a high-power rotating mechanism, while the concentrating collection method has an overall optimized system compared to the former, but it is complicated. Configuration and control are still a big problem
The latest and better overall system scheme adopts the idea of modularization and light weight, which reduces the pressure on control, but it is not easy to realize the directional control of a large number of small components

The invention discloses a zero refractive index material-based design method for a concentrated solar collection device. The design method comprises the following processes: firstly, determining the overall dimension and the structural shape of the solar collection device and the placement position of a cell array according to the requirements of track placement, input total power and mean input power of the solar collection device; secondly, carrying out partitioning optimization and fine tuning on the solar collection device by a ray tracing algorithm employing the distribution uniformity of the energy density on the cell array as an index; and finally obtaining the solar collection device with relatively good uniformity. A solar concentrator is used for collecting solar energy in a space solar power station and is relatively simple in overall structure and control; and the space solar energy collection efficiency can be improved.
Description
technical field [0001] The invention belongs to the technical field of manufacturing space solar energy collection devices, and in particular relates to a method for designing the structure of space solar energy collection devices using zero-refraction materials. The solar energy collection devices are used in space solar power stations to collect sunlight energy. The solar energy collection devices The whole structure and its control are relatively simple, which can improve the efficiency of space solar energy collection. Background technique [0002] Solar energy is a new type of renewable green energy. In addition to the shortage of earth resources and serious environmental pollution, if the efficient use of solar energy can effectively reduce the pressure on resources and the environment. Since the solar energy received by the earth is only 1 / 10-1 / 5 of the solar radiation energy in space, and due to the stripping of the atmosphere, the energy density is also greatly redu...
