Abstract
In-situ technique is used to generate cadmium sulfide nanoparticles in PVA matrix. The as-prepared films are characterized by X-ray diffraction, transmission electron microscopy, ultraviolet–visible absorption, Fourier transform infrared spectroscopy and photoluminescence measurements. Temperature dependence dark conductivity measurements are made on as-deposited PVA:n-CdS nanocomposites films in order to identify the conduction mechanism. The conduction in PVA:n-CdS nanocomposites films is temperature activated process having single activation energy. Steady state photo-conductivity and transient photoconductivity measurements with intensity are done in different temperature range. The measurement shows that PVA doped CdS is good candidate for photovoltaic devices.
