What causes small leakage currents in photovoltaic (PV) modules?
ABSTRACT: Small leakage currents flow between the frame and the active cell matrix in photovoltaic (PV) modules under normal operation conditions due to the not negligible electric conductivity of the module build-ing materials.
How do leakage currents affect PV module efficiency?
This will induce leakage currents flowing through the module package potentially leading to significant PV module efficiency loss. In standard p-type c-Si PV modules, leakage currents can flow from the module frame to the solar cells along several different pathways (Fig. 2), which are depicted as follows:12,13,44,48–50
How does dust affect the leakage current of a PV module?
A slight amount of dust (2 g/m2) on the module surface was found to trigger the wet leakage current to a considerable limit. Tiny dust particles have a capability to attach with some ionic compounds, where Na ions are dominant from the coastal area that prompts the leakage current of the PV module.
How does leakage current affect the performance of a solar cell?
A current is generated under this voltage stress, known as leakage current. Along with this leakage current, the availability of an adequate number of ions (i.e., Na+) on the solar cell surface leads to potential induced degradation (PID). This results in the degradation in the performance of a solar cell.
How are leakage current paths investigated in PV modules under high voltage bias?
A detailed investigation of the leakage current paths within the PV modules, under high voltage bias, is carried out by utilizing a device that measures the independent contributions of various paths in real-time.
Does surface temperature affect high-voltage-stress leakage current of crystalline PV module?
