Description

太空探测器用太阳电池阵的入射光角度调整模拟工装The incident light angle adjustment simulation tooling of the solar cell array for the space probe

技术领域technical field

本发明涉及空间卫星电源技术领域，特别是涉及一种太空探测器用太阳电池阵的入射光角度调整模拟工装。The invention relates to the technical field of space satellite power supplies, in particular to a simulation tool for adjusting the angle of incident light of a solar cell array for a space probe.

背景技术Background technique

嫦娥三号探测器由着陆器和巡视器组成，巡视器的任务目标是进行月面巡视科学探测。太阳电池阵是整器正常工作所需能量的直接来源，其主要功能是在月面工作阶段将太阳能转换成电能，通过电源控制器为整星平台及负载供电，同时能够满足蓄电池组的充电需求，使整星在阴影期仍然能够正常工作。在巡视器月面巡视过程中，太阳光入射到太阳电池阵的入射角变化范围大，为明确电池阵在大光照角入射条件下的输出功率，为整器功率平衡计算提供依据，在研制过程中进行了大光照角入射分析与验证工作。The Chang'e-3 probe consists of a lander and a rover. The mission goal of the rover is to conduct scientific exploration of the lunar surface. The solar battery array is the direct source of energy required for the normal operation of the whole device. Its main function is to convert solar energy into electrical energy during the working phase of the lunar surface, supply power to the whole star platform and loads through the power controller, and meet the charging needs of the battery pack. , so that the whole star can still work normally during the shadow period. During the patrolling process of the lunar surface of the patrol device, the incident angle of sunlight incident on the solar cell array varies widely. In order to clarify the output power of the cell array under the condition of large incident angle of light and provide a basis for the calculation of the power balance of the whole device, during the development process The incident analysis and verification work of large illumination angle was carried out in the paper.

与地球表面相同，在月面同样存在“日出”、“日落”的现象，只不过月球表面的一个白天相当于地球日15天的时间。因此，太阳光入射到太阳电池阵的入射角度在0°～90°之间变化。为明确电池阵在大光照角入射条件下的输出功率，为整器功率平衡计算提供依据，在研制过程中进行了大光照角入射分析与验证工作Similar to the surface of the earth, the phenomena of "sunrise" and "sunset" also exist on the surface of the moon, but one day on the surface of the moon is equivalent to 15 days on the earth. Therefore, the incident angle of sunlight incident on the solar cell array varies between 0° and 90°. In order to clarify the output power of the battery array under the condition of large light angle incidence and provide a basis for the calculation of the power balance of the whole device, the large light angle incidence analysis and verification work was carried out during the development process

在太阳斜射角上，太阳电池的功率输出能力将降低。太阳电池的短路电流将近似按照入射角的余弦值降低，而实际的最大功率降低则比余弦值的降低趋势更为迅速。一般来说，对于约30°或更小的偏离角来说，这些与余弦定律的不一致性是无关紧要的，但在光照角较大时，这些与余弦定律的不一致性较为严重，需要加强关注。At the oblique angle of the sun, the power output capability of the solar cell will decrease. The short-circuit current of the solar cell will decrease approximately according to the cosine value of the incident angle, while the actual maximum power decreases more rapidly than the cosine value. Generally, for off angles of about 30° or less, these inconsistencies with the law of cosines are inconsequential, but at larger illumination angles, these inconsistencies with the law of cosines are severe and require increased attention .

在较大入射角时，由于涂层和滤光层的光学厚度发生表观变化，因而引起光谱透射率和反射率的表观变化。光的边缘效应可能引起太阳电池和盖片、尤其是较厚的盖片发生折射、散射以及额外的光吸收。太阳电池的盖片边缘、太阳电池互联器、引线以及太阳阵的其它较小元件在太阳电池上形成的阴影，也会引起功率损失。At larger angles of incidence, apparent changes in spectral transmittance and reflectance are caused by apparent changes in the optical thickness of coatings and filters. Light edge effects can cause refraction, scattering and additional light absorption in solar cells and cover sheets, especially thick cover sheets. Shadows cast on the solar cells by the edges of the solar cell cover sheet, solar cell interconnectors, lead wires, and other smaller elements of the solar array can also cause power loss.
