PHOTOELECTROCHEMICAL CHARACTERIZATIONS OF SPRAY DEPOSITED NANOSTRUCTURED FeCdS3THIN FILMS

摘要

Nanostructured FeCdS3thin films were prepared by spray pyrolysis method using various complexing agents. The current voltage (I–V) characteristics of the films were studied for n-FeCdS3/ polysulfide /graphite photoelectrochemical cell configuration. The fill factor (FF) and efficiency (η) for the cell have been estimated. It was found that PEC cell formed with the film deposited from acetic acid complex shows improvement in Voc, Isc, FF and . %. The junction ideality factors, ndand n1was found 4.43 and 5.71 for EDTA and decreases to 4.04 And 5.39 respectively for the film deposited from acetic acid. The photovoltaic efficiency (η %) and fill factor (FF%) is 0.21 and 4.42 for the PEC cell formed from the FeCdS3 film deposited from EDTA complex and it increases to 0.41 and 43.47 respectively for cell formed from the film deposited using acetic acid
