Abstract
Kariman Hussein Mohamed Marzouk,” Effects of Radiation on 11-VI Thin Films”.
Doctor of Philosophy Dissertation, Ain Shams University, 2000.
The need for lightweight, rugged and reliable power source in
military and space applications, where devices are subjected to a variety
of radiation environments, shows the importance of studying the
radiation effects on some of the bulk semiconductor devices.
The main objective of the present work is to study the gamma
radiation effects on the prepared solar cells based on the II-VI materials.
Also, to investigate their radiation sensitive parameters.
Physical, optical and electrical characteristics of the Il- Vl
materials, such as CdTe, CdS, CdSe, ZnS and ZnSe, were studied. The
morphology of these materials were analyzed applying the x-ray
diffraction and the EDX analysis techniques. Also, the optical
characteristics were measured where the optical band gap of these
materials were calculated. The current-voltage relationship of these
materials were measured. f-rom which, the activation energy was
obtained from the variation of the conductivity with the temperature.
CdTe was chosen, from the above compounds, to be an absorber,
while CdS was chosen as a window for the proposed solar cell. Two
configurations were prepared using CdS/CdTe to study some of the
electrical properties of the cells. The two proposed samples were: the
[rontwall cell; with the arrangement of glass / CTO / CdS / CdTe, and
backwall cell; with the arrangement of glass / Au / CdTe / CdS. The
thermal evaporation method was the way of preparing these samples.
