Special Issue Information

Dear Colleagues,

Dust deposition on photovoltaic (PV) arrays is a critical issue that directly degrades energy conversion efficiency, increases operation and maintenance costs, and shortens the service life of PV systems, particularly in arid, semi-arid, and desert regions. With the rapid expansion of large-scale PV power plants in desert and Gobi areas, the accumulation of wind-blown sand and atmospheric dust on panel surfaces has become a major operational bottleneck, significantly reducing energy yield and increasing maintenance costs. Thus, understanding the coupled processes of sand-dust transport, deposition, adhesion, and resuspension on PV surfaces is essential for developing effective mitigation strategies. Addressing these challenges requires interdisciplinary approaches combining atmospheric physics, particle mechanics, surface engineering, and intelligent control.

This Special Issue on “Research on Photovoltaic Arrays and Dust Deposition” seeks high-quality works that focus on the latest advances in the interaction between sand-dust sedimentation and PV systems. Topics within the scope of this issue include, but are not limited to, the following:

  • Mechanisms of sand-dust transport, deposition, and adhesion on PV surfaces;
  • Numerical modelling of dust accumulation processes under windy and dusty conditions;
  • Field measurements and model-predicted power losses of PV systems;
  • Anti-soiling and anti-sand coatings for photovoltaic glass;
  • Automated dry/wet cleaning technologies for dusty environments;
  • Wind-sand flow fields around PV arrays and their influence on dust settlement;
  • Atmospheric dust deposition prediction;
  • Economic and life-cycle assessment of dust mitigation strategies for desert PV farms;
  • Optical properties of dust particles, including mechanisms of light transmittance attenuation in PV cover glass, non-contact soiling detection using spectroscopic techniques, and remote sensing inversion of dust deposition density.

Clarifying how vegetation restoration regulates wind erosion, sediment redistribution, and soil improvement is essential for ecological management in desert photovoltaic power stations. This study was conducted in a high-clearance flexible-support photovoltaic power station at the edge of the Kubuqi Desert. Three restoration measures were compared: reed mulch combined with Atriplex canescens planting along the panel front edge (M1), A. canescens planting along the panel front edge alone (M2), and reed mulch combined with grass seeding (M3). The panel front-edge zone (QY), under-panel zone (BX), and pedestal zone (JZ) were used as functional units to analyze surface sediment grain-size characteristics, soil moisture, soil nutrients, windbreak efficiency, aerodynamic roughness length, and cumulative sand-fixing efficiency. All restoration measures altered the surface sediment structure, with Mz ranging from 2.005 to 2.364 and D0 from 1.459 to 1.935. Soil moisture ranged from 0.58% to 4.34%, with the highest value occurring in the 20–30 cm layer of QY under M1. M1 also showed higher soil organic matter in QY and JZ, reaching 1.87 and 1.16 g·kg−1, respectively. Windbreak efficiency decreased with height under all measures. M1 maintained the highest and most stable values, decreasing only from 61.16% at 10 cm to 55.52% at 100 cm. The total cumulative sand-fixing efficiency was also highest under M1 (233.66%), while M2 (215.05%) and M3 (214.58%) showed comparable total effects but different zonal responses. Wind-eroded materials shifted from fine-sand dominance toward a higher relative contribution of medium sand, reflecting the reduction in finer transported fractions rather than true grain coarsening. The novelty of this study lies in linking wind-erodible sediment redistribution, soil water and nutrient responses, and windbreak–sand-fixing performance across internal functional zones of a flexible-support photovoltaic array. These results indicate that vegetation restoration in desert photovoltaic power stations should be configured by functional zone, with composite interception at the panel front edge, structural maintenance in the under-panel zone, and cover-based sand trapping in deposition-prone areas.
