The present work elucidates the successful attempts toward the development of a highly transparent, flexible, and superhydrophobic (HTFS) film. The HTFS film is obtained by introducing graphene oxide (GO) into micropillar‐patterned poly(urethane acrylate) (PUA), followed by siloxane functionalization via chemical vapor deposition. The fabricated SPG₂ film (siloxane‐functionalized PUA incorporated with 0.1 wt% of GO) exhibits a water advancing contact angle, water receding contact angle, and sliding angle of 155.5 ± 0.3°, 143.4 ± 0.6°, and 9 ± 0.4°, respectively. The SPG₂ film also exhibits an optical transmittance of ≈84% at 550 nm. Mechanical wearable tests demonstrate no significant degradation in the self‐cleaning properties and optical transparency. The fabricated HTFS film (SPG₂) is used as a protective layer for a solar module. This solar module shows improved power conversion efficiency (PCE) compared to that of a bare solar module owing to the high optical transparency and light‐trapping effect of the fabricated film that reduce the light reflectance. Furthermore, the SPG₂‐protected solar cell demonstrates superior PCE under different surface contamination conditions comparing to other cells. The fabricated micropatterned SPG₂ film can be used for various outdoor applications that require high optical transparency, flexibility, and superior self‐cleaning performance.

高柔韧性的超疏水聚丙烯酸聚氨酯膜，用于要求高光学透明性的应用

本工作阐明了开发高度透明，柔性和超疏水（HTFS）膜的成功尝试。HTFS膜是通过将氧化石墨烯（GO）引入微柱图案化的聚（氨酯丙烯酸酯）（PUA）中，然后通过化学气相沉积进行硅氧烷官能化而获得的。制成的SPG ₂膜（掺有0.1 wt％的GO的硅氧烷官能化PUA）显示出水前进接触角，水后退接触角和滑动角分别为155.5±0.3°，143.4±0.6°和9±0.4°，分别。SPG ₂膜在550 nm处的透光率也达到≈84％。机械耐磨性测试表明自清洁性能和光学透明性没有明显降低。制作的HTFS膜（SPG₂）用作太阳能电池组件的保护层。与裸太阳能模块相比，该太阳能模块显示出更高的功率转换效率（PCE），这是因为所制造的薄膜具有很高的光学透明度和陷光效果，从而降低了光反射率。此外，与其他电池相比，受SPG ₂保护的太阳能电池在不同的表面污染条件下表现出优异的PCE。制成的微图案SPG ₂膜可用于需要高光学透明度，柔韧性和出色的自洁性能的各种户外应用。
