Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
This research investigates the consistency of chemical bath deposition (CBD)
for CdTe thin films. Films were deposited using tellurium dioxide and cadmium acetate
in a non-aqueous medium at 160°C. The impact of subsequent annealing on the optical,
structural, and surface properties of these films was examined. XRD, FTIR, UV-Vis,
SEM, and photoluminescence techniques were used to characterize the films. EDS
analysis revealed a Cd:Te ratio of 1.27 before annealing, which improved to 1.06
(closer to the ideal 1:1 ratio) after annealing. The average crystallite size of annealed
CdTe film was around 25nm. Photoluminescence peaks were observed at 566 nm and
615 nm.
