Evaluation of Four Imaging Techniques for the Electrical Characterization of Solar Cells
Published online by Cambridge University Press: 21 March 2011
Abstract
We evaluate four techniques that image minority carrier lifetime, carrier diffusion length, and shunting in solar cells. The techniques include photoluminescence imaging, carrier density imaging, electroluminescence imaging, and dark lock-in thermography shunt detection. We compare these techniques to current industry standards and show how they can yield similar results with higher resolution and in less time.
