“…Abrasion tests were performed according to standard UNI EN 1096-2 on the Gardner Abrasion Tester equipped with a 10-mm wide felt insert with a density of 0.52 g/cm 2 . Prior to the tests, samples were washed in distilled water to remove impurities, then the tests were conducted with a weight experienced by the samples of 116 g. To assess abrasion resistance, WCA analysis was performed in 3 moments: (1) prior to the tests, (2) after 150 double strokes (back and forth), and (3) after 300 double strokes.…”

“…Photovoltaic (PV) capacity has reached 1 TW milestone in 2022 and is expected to double it in 2025, [1] with projections seeing the PV sector providing up to 25% of the world's energy in 2050. [2] This is due to the cost decline of PV panels with module prices having fallen 85% since 2010 and related electricity costs predicted to get cheaper by 40-50% by 2035. [3] Large PV installations are being installed in areas closer to the equator where irradiation is greater which translates into greater energy e ciencies and competitive costs.…”

An innovative hydrophobic (WCA ≥ 90°), transparent thin film is reported. It is applicable on any glass, ceramic, or metallic surface. Notably, it can be applied on photovoltaic panels, providing a solution for the soiling phenomena, and increasing their efficiency, in fact in pursuing the energy efficiency, the importance of careful maintenance of cleaned photovoltaic fields to preserve their efficiency is a key factor. The proposed new coating is based on organic-inorganic hybrid sol-gel formulations having two major advantages: (a) being applicable on any glass surface (photovoltaic, building glasses, automotive, marine, …); (b) being applicable directly in the field thanks to their fast-curing times (120 seconds or less) at ambient temperature. The good physical and chemical behaviour of the new coating has been verified by measures and tests such as Water Contact Angle (WCA), anti-soiling properties and durability.

“…Recently, several researchers from different regions have investigated the soiling effect on the PV module's performance. For instance, a new approach was suggested in the work of Araujo et al 57 to evaluate the dust and dirt accumulation on PV modules via a machine learning approach to enhance power production and efficiency of PV technologies. Five different machine learning models were employed.…”

Nowadays, renewable energies are capturing the world's attention, particularly in light of the phenomenon of climate change and carbon dioxide emissions, which have caused major environmental damage. As a result, many investors have recently focused on developing investments in renewable energy projects worldwide, specifically photovoltaic and concentrated solar power plant projects. These solar technologies are considered among the most profitable solutions for generating power from a natural, free, and unlimited energy source. This review paper discusses one of the most significant issues affecting the performance of these solar systems, which is known as soiling. It has been supported by several studies in various nations with different climatic conditions, which offered accurate empirical data on the degradation rate of photovoltaic and concentrated solar power systems’ production due to the soiling effect. Furthermore, it provides various mitigating soiling ways, including manual and autonomous cleaning methods for both solar technologies. Ultimately, it summarizes each cleaning technique's main advantages and drawbacks, specifying its applicability according to the location characteristics and climatic conditions. Additionally, the review results reported in this work are intriguing enough to warrant further development of concentrated solar power and photovoltaic technologies.
