摘　　要：为了最大化获取不同纬度月面的光伏资源,系统研究和优化了光伏板在不同纬度月面的倾斜角度.首先基于半解析轨迹理论建立了完整的月球轨道模型,计算得到月面全年的太阳辐射强度、太阳直射点等,进而针对月面以辐射换热为主的热环境,提出了耦合温度衰减效应的输出特性导向型光伏板最优倾斜角度的优化算法.结果显示:以“嫦娥四号”搭载的Ⅲ-Ⅳ族砷化镓光伏板为例,通过将光伏板倾斜角度增大以控制辐射热通量,在温度衰减系数0.004℃下,光伏板日间平均温度最高降低223 K,单位面积最大可输出电能平均优化率达63.51%;采用所提优化算法,月面光伏板单位面积最大可输出电能随着纬度升高呈现上升趋势,但在极点附近急剧下降,并在约85°达到峰值.To maximize the acquisition of photovoltaic(PV) resources on the lunar surface at different latitudes, the tilt angle of PV panels on the lunar surface at different latitudes was systematically studied and optimized. First, a complete lunar orbit model was established based on the semi-analytic trajectory theory, the solar radiation intensity and the direct sunlight points on the lunar surface were calculated for the whole year. Furthermore, an optimal tilt angle optimization algorithm for PV panels based on output characteristics coupled with temperature decay effect was proposed for the thermal environment dominated by radiation heat transfer on the lunar surface. The results show that taking the Ⅲ-Ⅳ GaAs PV panels on board Chang’e-4 as an example, by increasing the tilt angle of the panels to control the radiative heat flux, the average daytime temperature of the PV panels can be reduced by up to 223 K with a temperature decay coefficient of 0.004 ℃, and the average optimization rate of the maximum output power per unit area reaches 63.51%. Using the optimization algorithm, the maximum output power per unit area of the lunar surface PV panels shows an increasing trend with the increase of latitude, but decreases sharply near the pole and reaches the peak at around 85°.
