Abstract

This paper investigates the ways to detect defects in photovoltaic (PV) cells and panels. Here, two different methods have been used. First, the output behavior was characterized by measuring the amount of current at 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 use of synchronized thermography. From these measurements, temperature maps can be derived, which indicate that the temperature within a given PV cell unevenly rises due to the defects in the cell. Uneven temperature distribution indicates defects and reduced output power.
