Nanoscale structures based on the Zn$_{1-x}$Cd$_{x}$S

In this work, the results of the investigation of the precularity near the solar spectrum region, of Zn$_{1-x}$Cd$_{x}$S nanoparticles, nanofilms, nanoscale p-n and heterojunction prepared on glass-ceramic and alumminium substrates by precipitation from aqueous solutions are presented. We investigated the preparation of ZnCdS nanoparticles in a micro-emulsion system stabilized with nonionic surface active materials, as well as the impact of drop volume and supersaturation the size of the formed ZnCdS particles. The temperature dependence of dark and light conductivity, spectrum and optical quenching of primary and impurity photoconductivity were investigated. Direct current-voltage characteristic structure of Al/p-CdS/n-CdS is almost identical to the current-voltage characteristics of p-n junctions. Volt-farad characteristics of the samples established the presence of conduction due to the presence of reverse bias p-n junctions. In the following order, CdTe/CdS/Zn$_{1-x}$Cd$_{x}$S structure have 75% or slightly higher quantum efficiency in the 400–850 nm wavelength region.
