TL;DR: The international Task 13 expert team has summarized the literature as well as their knowledge and personal experiences on actual failures of PV modules, and introduces a signal transition method for the detection of defective circuits in installed PV modules.
Journal ArticleDOI
The risk of power loss in crystalline silicon based photovoltaic modules due to micro-cracks
TL;DR: In this paper, an upper bound for the potential power loss of PV modules due to micro-cracks in the solar cells was derived by simulating the impact of inactive solar cell fragments on the power of a common PV module type and PV array.
Journal ArticleDOI
Spatial and orientational distribution of cracks in crystalline photovoltaic modules generated by mechanical load tests
TL;DR: In this paper, the authors present a statistical analysis on the crack formation in 27 crystalline silicon PV modules caused by a standard mechanical load test according to IEC 61215 10.16.
Journal ArticleDOI
Detection of the voltage distribution in photovoltaic modules by electroluminescence imaging
TL;DR: In this article, an approach to determine the operating voltage of individual solar cells in photovoltaic (PV) modules by electroluminescence (EL) imaging was introduced.
Journal ArticleDOI
Light induced changes in the electrical behavior of CdTe and Cu(In,Ga)Se2 solar cells
TL;DR: In this paper, a model describing the influence of the illumination on the I-V and QE curves of CdTe and Cu(In x,Ga 1−x )Se 2 (CIGS) solar cells is presented.
