Chemical Deposition of CdS Films for Photoelectrochemical Solar Energy Conversion

Abstract

The properties of photochemical CdS film deposited on Cd substrates by chemical bath deposition method (in aqueous polysulphide solution) have been studied.The output characteristics of the cells Cd/CdS/0.1MS,0.1 M Na2S, 0.1 M NaOH /C have been measured. The maximum open circuit voltage and the short circuit current density have been observed as 0.39V and 315 A/Cm2 respectively. This is done by illuminating with light intensity of 65mW/Cm2 after doping with light.The efficiency of photoelectrochemical (PEC) cells using such polycrystalline CdS films is a bout an order lower than that obtained with single crystal CdS.
