Abstract
Spread spectrum time domain reflectometry (SSTDR) is a broadband electrical reflectometry technique that has been used to detect and localize faults on live electrical systems. In this paper, we use SSTDR to electrically interrogate the responses of PV cells and mini modules to three accelerated degradation tests: damp heat, potential induced degradation, and humidity freeze. The SSTDR responses change in distinct ways for each test demonstrating that SSTDR can be used to identify the type of accelerated degradation in cells.
