Title: Oxidative Segregation of Group V Dopants in CdTe Solar Cells

Abstract

Unless the scientific understanding and engineering of CdTe solar cell interfaces improve, the potential efficiency gains from improving the absorber lifetime and hole density will not be realized. We use thermomechanical cleaving, a new method of cleanly exposing interfaces, in conjunction with surface analysis methods to elucidate new aspects of CdTe solar cell structure and function. Liquid nitrogen-based thermomechanical, planar cleaving of devices and test structures in a glove box connected to a cluster tool allows surface spectroscopy of buried interfaces without contamination, oxidation, or perturbation of chemical environment.
