Influence of Spray Deposition Conditions on CuInS₂ Semiconductor Properties
Author : Vijendra A Chaudhari
Abstract :
Spray pyrolysis thin film deposition technique has been used to deposit CuInS2 type semiconductor thin films. The influence of various deposition parameters on the morphology and other properties has been extensively investigated. The structural, morphological, optical absorptions properties of the CuInS2 thin films have been systematically studied to understand the effect of various preparative parameters like Tc, pH and Cu/In ion ratio. It is observed that the parameters critical to structural and optical properties of sprayed CuInS2 films are Tc and ion ratio of Cu/In in the spraying solution. Here we report the effect of one of the critical parameter i.e. substrate temperature on the morphological characteristics and optical, electrical properties of the thin films deposited.
