Effect of annealing on the loss kinetics of charge carriers in CdS films

Abstract

Flow rate effect on surface morphology of Cu doped CdS thin film by spray pyrolysis technique AIP Conf. Swift heavy ion induced structural changes in CdS thin films possessing different microstructures: A comparative studyThe influence of the annealing treatment on the kinetics of the electron trapping processes in CdS thin films has been investigated using the contactless time-resolved microwave photoconductivity technique (TRMC) in 9 GHz band. The thin (<200 nm) CdS films were synthesized using two techniques: by the chemical deposition from the solution (CBD method) and by the pyrolysis of the aerosols of the aqueous solutions of the thiourea coordination compounds of cadmium (Cd(thio) 2 Cl 2 ) on a heated substrate. Annealing in both the air and the nitrogen atmospheres resulted in an increase of the amplitude and characteristic decay time of the photoresponse. Two particular effects caused by the annealing treatments were observed: the structural improvement and the energy redistribution of the electron traps. V C 2013 American Institute of Physics.

Preface to Special Topic: Selected Papers from the Photovoltaic Technical Conference, Aix en Provence, France, 2012

“…Rabenok et al 6 studied the influence of the annealing treatment on the kinetics of the electron trapping processes in CdS thin films by using contactless time-resolved microwave photoconductivity. The main idea behind this work is to gain a better understanding of the influence of the annealing of the CdS buffer layer on the characteristics of solar cells.…”

Chalcogenide nanostructures: Topography, synthesis, properties, and applications

“…They have presented a comprehensive review on the recent advances in the synthesis, properties, and optoelectronic applications of one-dimensional II-VI nanostructures, particularly approaches to manipulate the electronic, optoelectronic, and transport properties of II-VI nanostructures by controlled doping and the latest progresses in fabricating high-performance II-VI nanoelectronic and nanooptoelectronic devices. Rabenok et al 14 have investigated the influence of annealing treatment on the kinetics of electron trapping processes in CdS thin films using the contactless time-resolved microwave photoconductivity technique in the 9-GHz band. The thin (<200 nm) CdS films were synthesized using two techniques: by chemical deposition from solution (CBD method) and by pyrolysis of aerosols of aqueous solutions of thiourea coordination compounds of cadmium (Cd(thio) 2 Cl 2 ) on a heated substrate.…”

Research in the Field of Organic Photovoltaics at the Institute for Problems of Chemical Physics of Russian Academy of Sciences

“…Special attention was paid to design of novel materials for photography [51,52], exploration of colloidal systems including gold nanoparticles and quantum dots based on inorganic semiconductors such as CdS, CdSe and PbS [53,54]. Nanostructured systems based on inorganic semiconductors have being investigated as promising materials for solar cells [55][56][57]. Several families of transition metal complexes, aromatic polyamines and polymers were designed as promising materials for organic light-emitting diodes (OLEDs) [58][59][60][61].…”
