| Abstract: |
| 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. |
