Abstract

Luminescence imaging is widely used as ground truth for defect and fault detection in many instances of research and PV inspections. Cable handling and PV shading practices for field inspections can correspond to most of the inspection time and be responsible for the highest cost and safety concerns for the procedure. Performing photoluminescence (PL) during an IV sweep that has been already programed to happen in an inverter is an excellent strategy to reach high throughput for PV luminescence-based inspections without significant additional demands in terms of cost and inspection complexity. In this work, we present a detailed image quality analysis with image acquisition performed at different sun excitation intensities, show what is the level of image quality that can be achieved compared with daylight electroluminescence, and the available possibilities to acquire PL images during an inverter IV sweep procedure.
