摘要
We present a facile method for producing superhydrophobic nanograss-coated （SNGC） glass surfaces that possess both reduced reflectivity and self-cleaning properties at the air/glass interface. The refractive index of a CaF2 nanograss （NG） layer on a glass substrate, deposited by glancing angle vapor deposition, is 1.04 at 500 nm, which is the second-lowest value ever reported so far. The fluorinated NG layer gives rise to a high water contact angle （〉150°） and very efficient cleaning out of dust with water drops. Using the dual functionalities of the SNGC glass, we demonstrate superhydrophobic and antireflective organic photovoltaic cells with excellent power conversion efficiency.
我们在场为生产 superhydrophobic 的一个灵巧的方法 nanograss 涂(SNGC ) 在空气 / 眼镜拥有两个都减少的反射率和自我清洗的性质的玻璃表面连接。CaF 的折射索引 < 潜水艇 class= “ a-plus-plus ” > 玻璃底层上的 2 </sub> nanograss (NG ) 层，由看一眼的角度蒸汽免职扔了，在 500 nm 是 1.04，它是到目前为止曾经报导的秒低的价值。氟化的 NG 层产生一个高水位线接触角度(> 150 ?????
