Voltage-Based Hot-Spot Detection Method for Photovoltaic String Using a Projector

Voltage-Based Hot-Spot Detection Method for Photovoltaic String Using a Projector

This paper proposes a voltage-based hot-spot detection method for photovoltaic (PV) string using the projector. Hot-spots form in solar cells at defects causing a high carrier recombination rate, it appears as a high reverse leakage current of p-n junctions when solar cells are partially shadowed. U...
