Usage of Low Cost Digital Camera for Silicon Solar Cell Electroluminescence Detecting

Abstract

The goal of this article is focused on the developing of experimental measuring workspace used for diagnostic of solar cells and modules by electroluminescence detection. Electroluminescent imaging is increasingly used to detect defects in silicon solar cells. However, the cost of the conventional luminescence systems is a limiting factor for generalized use. A simple and reliable low-cost electroluminescence setup is presented. The developed system was tested on commercial silicon solar cells for the acquisition of electroluminescence images in the forward bias regimes.
