As environmental concerns associated with the usage of fossil fuels persist, solar energy is gaining recognition as a vibrant alternative energy, providing a means to minimize carbon emissions .Photovoltaic (PV) technology for electricity generation has become a promising method for electricity generation owing to its increasingly competitive commercial costs [2, 3].
Solar energy has gained prominence because of the increasing global attention received by renewable energies. This shift can be attributed to advancements and innovations in solar cell technology
The photovoltaic (PV) market started in 2000, and the first batch of crystalline silicon (c-Si) PV panels with a lifespan of 20–30 years are about to be retired. Recycling Si in waste c-Si PV panels is critical for resource reuse and environmental preservation. Electrostatic separation is a non-polluting and low-cost technology for recovering Si from mechanical
Renewable energy sources such as hydro energy, wind energy, and solar energy will cater to the high energy demands in the future. Solar cells can convert solar energy into electricity in an efficient way. They are popular because they are affordable, require little maintenance, and are environment friendly, .

The hydrophobic coating capable to remove the dust particles by using natural air only. The high speed-wind improves the self-cleaning process, later enhances the overall efficiency of coated PV panel. At the same time, its anti-reflection properties can reduce the temperature of the coated PV panel by 10°C as compared to the uncoated PV panel.
Solar panel repair is essential to maintain the performance of a solar array and prolong its lifespan. The solar cells, responsible for converting sunlight into electricity, are protected by a glass cover and aluminum frame. However, solar panels are still susceptible to issues that cause them to be less effective or even break and become unusable. Some of the
A typical c-Si solar PV module is made up of several silicon (Si) cells connected in series, which are the key components of the module. The cells are encapsulated between two sheets of polymer (EVA − Ethylene Vinyl Acetate) and a front glass on top and a backsheet, which is a combination of polymers (PET: Polyethylene terephthalate and PVDF:
