| 目的 减少月尘在光伏玻璃表面的沉积，提高光伏玻璃的自清洁性能，为月球车用太阳能光伏电池提供设计依据。方法 在光伏玻璃表面制备了形状规则、排布均匀的圆形、正方形和正六边形柱状凸起表面微织构。使用火山灰岩石制备模拟月尘颗粒来代替月尘进行试验。搭建月尘沉积试验系统，在不同工作角度、不同月尘量下，使用含有表面微织构的设计试样和不含表面微织构的对比试样进行月尘沉积试验。月尘沉积试验后，使用金相显微镜观察表面微织构试样和对比试样，统计月尘沉积量并进行比较分析。结果 不同工作角度以及不同月尘量下，3种结构形状的表面微织构均可以有效减少月尘在光伏玻璃表面的沉积，具有良好的自清洁性能。在工作角度为30°、45°、60°下，随着工作角度的增加，表面微织构的自清洁性能逐渐增加。工作角度为60°时，圆形表面微织构的月尘沉积量为对比试样的21.74%，正方形表面微织构的月尘沉积量为对比试样的26.92%，正六边形表面微织构的月尘沉积量为对比试样的18.64%。在月尘量为3、5、7 g下，随着月尘量的增加，表面微织构的自清洁性能先增强后减弱。月尘量为5 g时，圆形表面微织构的月尘沉积量为对比试样的26.71%，正方形表面微织构的月尘沉积量为对比试样的26.43%，正六边形表面微织构的月尘沉积量为对比试样的19.24%。3种结构形状的表面微织构中，正六边形表面微织构的自清洁性能最好，圆形表面微织构次之，正方形表面微织构最差。结论 通过在光伏玻璃表面制备出表面微织构，可以减少月尘在光伏玻璃表面的沉积，增强光伏玻璃的自清洁性能。 |

| This work aims to reduce the lunar dust on the surface of photovoltaic glass and improve the self-cleaning performance, which can provide a design basis for solar photovoltaic cells for lunar rover. On the surface of photovoltaic glass, columnar protruding micro-textures of circular, square and regular hexagonal with regular shapes and uniform arrangement were prepared. Volcanic ash rocks were used to prepare simulated lunar dust to replace the lunar dust for testing. The experimental system of lunar dust deposition was established. The design samples with surface micro-textures and the contrast samples without surface micro-textures were carried out the experiments of lunar dust deposition under different working angles and different amounts of lunar dust. Metallographic microscope was observed the micro-textures and contrast samples after the lunar dust deposition test, and the amount of lunar dust deposition was counted, compared and analyzed. The results showed that under different working angles and different amounts of lunar dust, the surface micro-textures with three structural shapes could reduce the deposition of lunar dust on the surface of photovoltaic glass, thus providing a good self-cleaning performance. As the working angle increased at 30°, 45° and 60°, the self-cleaning performance of the surface micro-textures was gradually enhanced. When the working angle was 60°, the amount of lunar dust deposition on the circular surface micro-textures was 21.74% of that on the contrast sample, and the amount of lunar dust deposition on the square surface micro-textures was 26.92% of that on the contrast sample, and the amount of lunar dust deposition on the regular hexagonal surface micro-texture was 18.64% of that on the contrast sample. With the amount of lunar dust were relatively 3 grams, 5 grams, and 7 grams, as the amount of lunar dust increased, the self-cleaning performance of the surface micro-textures first increased and then decreased. When the amount of lunar dust was 5 grams, the amount of lunar dust deposition on the circular surface micro-textures was 26.71% of that on the contrast sample, and the amount of lunar dust deposition on the square surface micro-textures was 26.43% of that on the contrast sample, and the amount of lunar dust deposition on the regular hexagonal surface micro-textures was 19.24% of that on the contrast sample. Among the surface micro-textures of the three structural shapes, the self-cleaning performance of the regular hexagonal surface micro-texture is the best, which is followed by the circular surface micro-texture, while the square surface micro-texture is the worst. |
