Description
Solar cells exhibit flaws that limit both their efficiency and their lifespan. Using luminescence images, a great deal of sample data can be obtained. This technique was considerably developed in the last years, because it is a non-destructive low-cost method and the required tools are simple. We have developed a compact equipment that facilitates a quick, comfortable and repetitive characterization. Its main purpose is to obtain luminescence (both photo and electroluminescence) images of silicon solar cells and wafers, using a camera equipped with a silicon or an InGaAs sensor. The analysis of the resulting luminescence images allows to characterize the samples according to the number of their flaws.Other information
