The resultant structures exhibited low reflections of less than 0.5%, and high static water contact angle (WCA) of larger than 160°.
When wavelength of optical pump is 400 nm, the microcavity will have low reflection for a large range of incident angles.
The reflective result shows that the MOS-structure solar cell with a 50-nm ITO/10-nm SiO2 layer exhibited good antireflective (AR) performance and that the low reflection band of the reflective spectrum matched the high energy band of the solar energy spectrum.
The PASiNP arrays show excellent antireflection property and give a low reflection loss of 2.84% within the wavelength range of 200 1,000 nm.
The typical sub-wavelength structure of PASiNP arrays had excellent antireflection property with a low reflection loss of 2.84% for incident light within the wavelength range of 200 1,000 nm.
However, the effectiveness of existing surface recovery algorithms is easy to be affected by some conditions like mechanical vibrations, low-reflection of the test surface and phase change caused by the reflection.
To satisfy the diverse requirements of low reflection and high absorption of microwave attenuation, the construction of multiple heterojunction structure is imperative.
