Outdoor photoluminescence imaging of solar modules
Outdoor contactless extraction of individual cell's I-V characteristics from solar modules
Why is your research important?
Photovoltaic (PV) modules are prone to damages during transportation, installation and operation leading to high demand for module inspection in the field. Photoluminescence (PL) is a very powerful characterization method that can provide high resolution spatially resolved information of cells and modules in a contactless manner. One of the main challenges associated with luminescence-based outdoor module inspection is the strong ambient sunlight. During the course of my Ph.D., I developed the first-ever PL imaging system to characterize PV modules in full sunlight without requiring any modification to the PV system.
I-V measurement of individual solar cells in a degraded module provides more accurate and specific information regarding the nature of faults identified by PL imaging, leading to a detailed understanding of the underlying detrimental recombination mechanisms. I developed a contactless and non-destructive method that is based on Suns-photoluminescence measurements to extract the current-voltage characteristics of individual solar cells under operating conditions in the field. The main advantages of this technique include its low cost, as well as its fast and easy applicability.
