More details: Films of CuxS with 217-502 nm thickness were deposited by Automatic Spray Pyrolysis technique, at T'5-325??C, from water:ethanol:glycerol:2:1 (in volumes) solutions with molar ratio Cu:S2.5-3.5. Relative dense, homogenous and uniform films of CuxS (x2), containing copper-rich phase digenite (single, predominant or secondary crystalline phase), with Eg41-3.1eV and exhibiting electric resistance behavior were obtained. The optimized CuxS layers were integrated in 3D solar cells which show the diode behavior but the photovoltaic response is very low, in the experimental conditions. ?? 2009 Published by Elsevier Ltd.Automatic spray pyrolysis,Copper sulfides,Solid state solar cells,Thin films,p-type absorbers
