Micro-structural defects in thin film photovoltaic devices

The efficiency of thin-film PV is limited by atomic-scale defects in the material (grain boundaries, planar defects, point defects etc). The manufacture of a high efficiency cell typically requires some form of defect passivation treatment, although exactly how these treatments work is not well understood. In this project, advanced characterization techniques will be used to study defects in thin film CdTe, CIGS, CZTS and perovskites deposited using different techniques. The project aims to determine how atomic-scale defects collectively degrade cell efficiency and the fundamental mechanisms underpinning their passivation. From this strategies for higher efficiencies can be developed. Electron microscopy is the primary characterisation tool, since it enables simultaneous structural, chemical and electrical property measurement on nearly every class of defect.
