Electron paramagnetic resonance as a probe of technologically relevant processing effects on CdTe solar cell materials

Abstract

The performance of polycrystalline thin film CdTe solar cells is limited by as yet poorly understood deep level defects which serve as recombination centers. Electron paramagnetic resonance (EPR) has unrivaled analytical power and sensitivity in the identification of deep level defects in semiconductors; however, very little EPR literature exists with… (More)
