Defect Detection and Degradation Analysis in Photovoltaic Modules using Thermography, Spectroscopy, and Current–Voltage Measurements, and Quantitative Assessment of Their Impact
Abstract:The measurement of defects in photovoltaic (PV) module and their impact assessment can help to improve the reliability and performance of PV systems. Herein, improved defect detection and degradation analysis approach using the combination of infrared (IR) thermography, electroluminescence emission spectroscopy, and current–voltage (I–V) measurements are presented. Moreover, an image‐processing scheme to automatically detect and compute defective area is also proposed. First, experiments are conducted on norma… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
