Embodiment Construction

[0046] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0047] The invention proposes a method for measuring battery output characteristics to calculate and calibrate the receiving spectrum of thermal photovoltaic cells by using mixed arrangement of photovoltaic cells and thermal photovoltaic cells with different absorption spectra. The significance of this method mainly lies in the following three aspects: 1. In the early stage of design, without the support of experimental data of various components, this method can provide reference for the calibration of parameters such as thermal light source radiation temperature and thermal photovoltaic cell absorption spectrum; 2. It is applicable to the comparative analysis of the efficiency of thermal photovoltaic thermoelectric conversion systems with different gray body radiator materials, different operating temperature, different energy sources, and different spati...

Abstract

The invention discloses a thermophotovoltaic power generation system spectral measurement method, which is characterized in that thermophotovoltaic cells are arranged around an isotope heat source anda radiation emitter, photoelectric conversion is carried out by absorbing infrared light waves emitted by the isotope heat source and the radiation emitter, and if a spectral measurement device is designed on the surface of the thermophotovoltaic cell, the spectral utilization efficiency of the thermophotovoltaic cell can be reduced. According to the method disclosed by the invention, photovoltaic cells with various spectra are arranged in the areas with oblique radiation light, weak light intensity and unavailable thermophotovoltaic cell distribution, so that the thermophotovoltaic cell caneffectively utilize the area with the strongest light intensity of the radiation spectrum, and the absorption of the radiation spectrum is not influenced.

Description

technical field [0001] The invention belongs to the technical field of space power sources, and in particular relates to a spectral measurement method for a thermal photovoltaic power generation system. Background technique [0002] Space isotope power supply technology refers to the power supply technology that uses the decay heat of radioactive isotopes as the energy source to generate electrical energy for aircraft missions through thermoelectric conversion power generation devices. It is mainly used to solve the energy problems of aircraft that are mainly used in deep space exploration and are not suitable for using solar energy. Efficient and stable isotope power generation technology is one of the core technologies for the development of deep space exploration. There are many forms of thermoelectric conversion power generation devices used in isotope power sources. Among them, thermoelectric power generation has been applied in many deep space detectors at home and ab...
