Abstract/Summary:

---

In this work, the durability of a novel anti-reflective photovoltaic glass surface is going to be analysed. Subwavelength structures (SWSs) on glass surface have shown an enhanced broadband omnidirectional antireflective property, increasing the transmittance up to values higher than commercial PV glasses with anti-reflective coatings (ARC). Although some research has been done with respect to the anti-reflective and anti-soiling properties of these structured glasses, abrasion resistance measurements is still missing. To this aim, this study demonstrates the durability of these SWSs against dry abrasion. In this respect, abrasion produced by Nylon brushes with and without Arizona Test Dust A2 standard dust has been quantified. The reduction of the anti-reflectance porperty in function of brushing cycles (100, 200, 300 and 500) has been characterized. Additionally, the damage produced to the SWS has been visualized through SEM images.
