Degradation mechanism of Al2O3 passivation in nanostructured Si solar cells
Abstract
The degradation mechanism of Al2O3 passivation on nanostructured Si is resolved by separate considerations of interface state density and fixed charge density at the interface of Al2O3/Si. Using the analysis of surface potentials, it is reported for the first time that the positive interface charges seriously deteriorate the field-effect passivation of Al2O3 on a nanostructured surface.
