[0030] figure 1 It is a schematic diagram of a traditional stacked multi-junction concentrating solar cell. The materials of each layer of a stacked solar multi-junction concentrating cell need to meet lattice matching and band gap matching, so as to achieve high conversion efficiency and high reliability. Lattice matching and forbidden band width matching are often contradictory, and it is dif...

Abstract

The invention discloses a simulation modeling method for a chromatic dispersion condensation type solar power system. The method comprises the steps: (1) utilizing a simple solar atmosphere radiation transmission mode for obtaining incident solar spectrums and radiation intensity data; (2) carrying out film system design, and obtaining the output spectral range and the output transmission/reflection rate of the input spectrums; (3) setting up a real system model for system modeling, and obtaining the projection spectral data and the radiation intensity data of solar sub-cells; (4) setting up a uni-junction/multi-junction solar sub-cell model used by a system, and obtaining output response of the sub-cells; (5) respectively calculating the efficiency of each sub-cell according to the output response and the projection spectral data of the sub-cells, and obtaining the generating capacity and the actual efficiency of the whole system. According to the method, actual incident cell surface spectral characteristics and the light intensity data can be obtained, the cell dosage concentration, the PN junction depth and the diffusion length parameters can be optimized, and battery packs good in compatibility can be well designed.

Description

technical field [0001] The invention belongs to the technical field of solar photovoltaic power generation, and in particular relates to a simulation modeling method for a dispersion-concentrating solar power generation system. Background technique [0002] Among the many energy sources we face, solar energy is undoubtedly the most abundant and reliable energy source. If 1% of the sun's energy incident on the earth is converted into electricity with an efficiency of 0.5%, the power generation will also exceed 40 times the total global energy consumption. Conventional flat-panel solar technology can achieve a conversion efficiency of more than 10% in actual use, while the occupied area is only about twice the module area, which means that the energy conversion efficiency per unit area of ​​land is 5%. [0003] However, since the actual usable land area is only 1 / 4 of the global area, the actual unit area can only produce a conversion efficiency of 1.35%. And considering tha...
