摘要: This paper is focused on the basic study and optimization of short time (<10 min) Chemical Bath Deposition (CBD) Zn(S,O,OH) buffer layers in co-evaporated Cu(In,Ga)Se2 (CIGSe) electrodeposited CuIn(S,Se)2 ((ED)-CIS) solar cells for industrial applications. First, influence deposition temperature studied from theoretical solution chemistry considerations by constructing solubility diagrams ZnS, ZnO, Zn(OH)2 as a function temperature. In order to reduce under 10 min, experimental growth studies are then carried out situ quartz crystal microgravimetry (QCM) technique. An optimized process performed compared classical deposition. The morphology composition films determined using SEM XPS techniques. tested electrodeposited-CIS co-evaporated-CIGSe absorbers completed with (Zn,Mg)O/ZnO:Al windows layers. Efficiencies similar or even better than CBD CdS/i-ZnO reference obtained (15·7% CIGSe 8·1% (ED)-CIS). Copyright © 2009 John Wiley & Sons, Ltd.
