TLDR
In this paper, infrared thermography (IR) was used to map the surface temperature distribution of solar cells while in the reverse bias mode, and it was observed that some cells exhibited an inhomogeneity of the surface temperatures resulting in localized heating (hot-spot).About:

Conventional and advanced PV array configurations to extract maximum power under partial shading conditions: A review
TL;DR: In this article, an overview of the state-of-the-art developments of various PV array configuration models for photovoltaic (PV) systems has been presented.
Journal ArticleDOI
Hot spot detection and prevention using a simple method in photovoltaic panels
TL;DR: In this article, a simple technique is proposed for detection of hot spotting also, an efficient method is utilised for protection of the panels against hot spotting The detection method is based on equivalent DC impedance (EDCI) of the panel's strings, which has useful signatures for hot spot detection.

Passive and Active Thermographic Assessment as a Tool for Condition-Based Performance Monitoring of Photovoltaic Modules
TL;DR: In this article, an assessment of infrared thermography as a photovoltaic (PV) module's condition monitoring and performance evaluation method was performed using the idea that any abnormality to the temperature pattern of an under inspection equipment implies a dysfunction case.
Journal ArticleDOI
Deterioration Diagnosis of Solar Module Using Thermal and Visible Image Processing
TL;DR: An image processing technique is introduced that automatically identifies the module generating the hot spots in the solar module and derives the area of interest by using the inrange function, using the blue color of the PV module.
Journal ArticleDOI
Rapid diagnosis of hot spot failure of crystalline silicon PV module based on I-V curve
TL;DR: Wang et al. as discussed by the authors proposed a hot spot fault diagnosis method based on I-V curve of PV modules, which is based on distance calculation between scan points and lines formed by the points.

Shunt Types in Crystalline Silicon Solar Cells
TL;DR: In this article, nine different types of shunt have been found in state-of-the-art mono and multicrystalline solar cells by lock-in thermography and identified by SEM investigation.
Proceedings ArticleDOI
Hot spot investigations on PV modules-new concepts for a test standard and consequences for module design with respect to bypass diodes
TL;DR: The selection of the worst case cell should be improved by measurement of the module current at the characteristic break point of the I-V characteristic, and the hot-spot test procedure of IEC 1215 should be generalised for all types of cell interconnection circuits.

Transition-metal profiles in a multicrystalline silicon ingot
TL;DR: In this paper, the concentrations of transition-metal impurities in a photovoltaic-grade multicrystalline silicon ingot have been measured by neutron activation analysis, and the results show that the concentration of Fe, Co, and Cu are determined by segregation from the liquid-to-solid phase in the central regions of the ingot.
Proceedings ArticleDOI
Applications for infrared imaging equipment in photovoltaic cell, module, and system testing
TL;DR: In this paper, the authors use portable infrared imaging systems (cameras) to measure both absolute and relative temperature distributions on small and large components with a high degree of temperature and spatial resolution.
