PROJECT TITLE :
Detecting Defects in Photovoltaic Cells and Panels and Evaluating the Impact on Output Performances
This paper investigates the ways to detect defects in photovoltaic (PV) cells and panels. Here, two totally different strategies are used. Initial, the output behavior was characterized by measuring the number of current at completely different voltage levels to obtain the current–voltage and power–voltage curves. Second, infrared emissions of forward-biased nonilluminated PV cells and panels were measured by the employment of synchronized thermography. From these measurements, temperature maps will be derived, that indicate that the temperature within a given PV cell erratically rises because of the defects in the cell. Uneven temperature distribution indicates defects and reduced output power.
