火星表面散射光对太阳电池发电影响研究

Effect of scattered light on surface of Mars on solar cell power generation

火星表面存在大气,太阳光经过大气后,部分被大气吸收,部分光到达火星表面,形成直射光,还有一部分光被空气尘埃阻挡发生漫反射,形成散射光,地面反射的光也是散射光光源的一部分。直射光和散射光均会对火星车太阳电池发电产生影响。分析了火星探测漫游者(MER)任务中火星车太阳翼实际发电情况,调研了火星表面直/散光辐照数据,进行了地面直/散光辐照试验,并对上述三类数据进行比对,给出火星表面散射光对太阳电池发电影响的定量结果。

There is atmosphere on the surface of Mars.After sunlight passes through the atmosphere,it is partially absorbed by the atmosphere,some of the light reaches the surface of the Mars to form direct light,and some of the light is blocked by air dust,resulting in forming scattered light.The light reflected on the ground is also part of the scattered light source.Both direct and scattered light can affect the power generation of the Rover solar cell.The actual power generation of the solar wing of the MER Rover was analyzed,and the irradiation data of direct and scattered light on the surface of Mars was investigated and tested.The quantitative results of the effect of the scattered light on the surface of Mars on solar cell power generation were given through comparing the above three types of data.
