Objectives
PbS/CdS/ITO and CdTe/CdS/ITO multilayer photovoltaic cells are ubiquitous in many
applications, from sensors to solar cells. Their physical and optical properties can be tuned by adjusting the
thickness of the various layer and can be modified by irradiating them.

The objectives of this WP are:

1) to synthesize PbS, CdS, CdTe, and ITO layers, and PbS/CdS/ITO and CdTe/CdS/ITO multilayers via RF
Sputtering and contribute to understanding the growth process

2) to determine crystal structure, physical and chemical properties of the individual layers as a function of
thickness, and the structure and properties of the interfaces in PbS/CdS/ITO and CdTe/CdS/ITO.

3) to determine the properties of point defects in multilayer samples before and after gamma, p+ , and alpha
irradiation.

4) to determine the physical and chemical properties of irradiated samples.
