Photovoltaic Cell: Photovoltaic cells consist of two or more layers of semiconductors with one layer containing positive charge and the other negative charge lined adjacent to each other.; Sunlight, consisting of small packets of energy termed as photons, strikes the cell, where it is either reflected, transmitted or absorbed.
Due to its simple fabrication process and low cost, dielectric ARC is widely used in commercial PV cells. However, it should be noted that the optical performance of single layer ARC is dependent on wavelength and polarization, and it has limited angular optical response which can be a drawback in practical applications .

Any arc fault in PV panels can cause variation of the reflection coefficient because of the changing arc impedance, which means the reflected signal from the fault terminal will change over time as well. Then, SSTDR is introduced to calculate the autocorrelation value using both V + and V − to detect arc faults. The SSTDR hardware scans the
Various factors can contribute to arc faults in a photovoltaic system, such as loose connections, inadequate breaker maintenance, broken cables, aging or damaged insulation materials, or the presence of damp and corrosive wires. Due to the numerous wires on the DC side of the PV system, arc faults are more likely to occur.
