Summary: Solar photovoltaics is a significant source of renewable energy, and the installed capacity of PV modules has exceeded 1TWp worldwide. However, these modules experience reflection losses at the front glass surface, which can be mitigated by anti-reflection coatings. This review examines the different types of anti-reflection coatings for solar modules and discusses their durability and potential alternatives.

Summary: The study revealed that adhesion force is related to surface energy, with organic and carbon-based materials more easily adhering to glass surfaces. The developed generalized linear model confirmed that the type of material should be included in soiling models as a variable, providing information on the likelihood of particles sticking to and remaining on the surface.

Summary: The aim of this study is to compare the soiling on hydrophobic coatings with and without dew suppression. The results show that under dew suppression, the hydrophobic coating reduces soiling by 50% (±13%) compared to the hydrophobic coating without dew suppression. Additionally, the hydrophobic coating (under dew suppression) reduces particle deposition by 60.0% (±8.1%) in the 10 to 30 μm range compared to uncoated slides (under dew suppression). However, the dust potency for uncoated and coated samples is statistically similar.

Summary: The study focuses on comparing the durability of three different PV panels in two regions under different climatic stresses. Influence of soiling on the panels was found to be significant, leading to a 29% drop in maximal power after one month of outdoor exposure. Aging of the panels was also studied over a period of around 1000 days, with an annual power loss recorded in both sites.

Summary: This study utilized the sol-gel method to prepare rough surface hydrophobic coating, successfully addressing soiling issues on PV panels. Different compositions of titanium alkoxide were used to create two sets of coated samples, and the CMTA sample showed the best hydrophobic characteristics based on contact angle, surface roughness, and optical transmittance analysis.

Summary: Metal halide perovskite solar cells (PSCs) show great potential as a low-cost thin-film photovoltaic technology. To ensure their commercialization, it is important to understand their reliability under real-world outdoor conditions. This study demonstrates that indoor accelerated stability tests can predict the performance of PSCs in outdoor environments. The degradation rates under illumination and elevated temperatures are found to be the most informative for assessing device reliability. The study also identifies the interface between indium tin oxide/self-assembled monolayer-based hole transport layer and perovskite layer as a key factor affecting device stability.

Summary: The integration of photovoltaic technology with agriculture in hot and arid climates can increase crop yield and reduce water use while meeting growing food and energy demands. Dynamic tilt control can eliminate shade effects on crops and soil moisture, but may increase system cost and complexity. Vertical bifacial AV farms show promise for shade-sensitive crops and climates with high PV losses due to dust.

Summary: One of the main challenges faced by solar asset managers is the accumulation of soiling and cementation on the photovoltaic module glass cover. While hydrophobic coatings have the potential to reduce soiling, concerns about their degradation in the field remain. Accelerated environmental exposure tests are important for understanding the degradation mechanisms and comparing them with long-term outdoor counterparts.

Summary: The objective of this review paper is to provide an overview of the current state-of-the-art in solar road deployment, including the availability of anti-reflection and anti-soiling coating materials for photovoltaic (PV) technology. By analyzing the existing literature on solar roads and PV materials, including anti-reflection and anti-soiling coatings, we aim to identify gaps in knowledge and propose an action plan to improve the resiliency, durability, and reliability of PV panels in solar road applications. This will enable the deployment of solar roads as a clean, renewable energy source.

Summary: In this study, sol-gel hydrophobic silica coatings modified with fluorine-free or fluorine-containing organosilanes were investigated for their resistance to UV radiation by examining changes in wettability, optical properties, surface morphology, and chemical composition. The results showed that the fluorine-containing organosilane modification significantly improved the UV resistance of the coatings.

Summary: Motivated by the increasing deployment of bifacial monocrystalline-silicon photovoltaics, this study investigates the durability of various PV module packaging configurations with transparent coverings, highlighting degradation modes including shunting, enhanced recombination, and series resistance increases. The research shows that multiple potential-induced degradation and moisture-ingress degradation modes severely affect EVA-containing modules, while minimal degradation is observed in POE-containing modules under all stress conditions.
