ABSTRACT: Dust deposition on the surface of photovoltaic (PV) cells poses a
significant challenge to their efficiency, especially in arid regions
characterized by desert and semi-desert conditions. Despite the pronounced
impact of dust accumulation, these regions offer optimal solar radiation and minimal
cloud cover, making them ideal candidates for widespread PV cell deployment.
Various surface cleaning methods exist, each employing distinct approaches.
Choosing an appropriate cleaning method requires a comprehensive understanding
of the mechanisms involved in both dust deposition on module surfaces and dust
adhesion to PV cell surfaces. The mechanisms governing dust deposition and
adhesion are complex and multifaceted, influenced by factors such as the nature
and properties of the dust particles, environmental climatic conditions,
characteristics of protective coatings, and the specific location of the PV
installation. These factors exhibit regional variations, necessitating the
implementation of diverse cleaning approaches tailored to the unique conditions
of each location. The first part of this article explores the factors
influencing dust deposition on PV cell surfaces, delving into the intricate
interplay of environmental variables and particle characteristics.
Subsequently, the second part addresses various cleaning methods, offering an
analysis of their respective advantages and disadvantages. By comprehensively
examining the factors influencing dust accumulation and evaluating the
effectiveness of different cleaning strategies, this article aims to contribute
valuable insights to the ongoing efforts to optimize the performance and
longevity of photovoltaic systems in diverse geographical contexts.
