Original Abstract

This paper is intended to present the results of our experimental study of local defect in silicon solar cells. Solar cells defects are evaluated by Near-field optical induced photocurrent, scanning near-field optical microscope characterization and noise spectroscopy. Low frequency noise is a more sensitive tool for analyzing of degradation phenomena, like electro migration and sort of breakdown. All type of noise - thermal, shot, generation, recombination and 1/f type of noise play a different role in reliability analysis. The correlation between noise and transport characteristic indicates possibility of this diagnostic tool. Therefore the SNOM, NOBIC and noise spectroscopy represent the coupling of very useful methods to provide a non-destructive characterization on silicon semiconductor solar cells.
