Auger electron spectroscopy study of alloy formation on MIS solar-cell metal surfaces

Abstract

The alloy formation on MIS solar cell metal surfaces due to the drive-out diffusion have been studied here. Au and Ag were used as metal electrodes, SnO2 as an interfacial layer, and GaAs as a substrate. These microscopic reactions at the interface and at the front metal surface are related to the performance and the stability of the GaAs, MS, and MIS solar cells.
