由于三维纳米结构可以显著提高光子的吸收能力,因此被广泛应用于各种光伏器件中。然而,传统的三维纳米结构成本高、制备工艺复杂,极大地制约了其发展。本文采用简单模板法在聚二甲基硅氧烷(PDMS)衬底上制备了一种新型纳米锥簇结构。这种新型纳米锥簇结构可以显著提高透光率,减少光反射,具有优异的抗反射性能。在整个可见光波段范围内,纳米锥簇结构有效地降低了光的反射率,使其保持在3.5%以下。此外,这种簇状微观结构具有良好的超疏水性和自清洁能力,接触角为151°。
As three-dimensional (3D) nanostructures can significantly improve the absorption capacity of photons, it is widely used in various photovoltaic devices. However, the high-cost and complex preparation process of traditional 3D nanostructures restricted its development greatly. In this paper, a new type of nanocone cluster microstructure was prepared on polydimethylsiloxane (PDMS) substrate by using a simple template process. This novel nanocone cluster microstructure can significantly improve the light transmittance and reduce the light reflection, showing superior anti-reflection property. In the whole range of visible band, the nanocone cluster microstructure effectively reduces the reflectivity of the light, so that it remains below 3.5%. In addition, this kind of cluster microstructure showed excellent superhydrophobic property and self-cleaning ability with the contact angle of 151°.
