the zn s o oh znmgo buffer in thin film cu in ga s se 2 based solar cells part i fast chemical bath deposition of zn s o oh buffer layers for industrial application on co evaporated cu in ga se2 and electrodeposited cuin s se 2 solar cells
Progress in Photovoltaics, 2009Co-Authors: C Hubert, N Naghavi, O Roussel, Arnaud Etcheberry, Dimitrios Hariskos, Richard Menner, Michael Powalla, O Kerrec, Daniel LincotAbstract:This paper is focused on the basic study and optimization of short time (<10 min) Chemical Bath Deposition (CBD) of Zn(S,O,OH) buffer layers in co-evaporated Cu(In,Ga)Se2 (CIGSe) and electrodeposited CuIn(S,Se)2 ((ED)-CIS) solar cells for industrial applications. First, the influence of the deposition temperature is studied from theoretical solution chemistry considerations by constructing solubility diagrams of ZnS, ZnO, and Zn(OH)2 as a function of temperature. In order to reduce the deposition time under 10 min, experimental growth deposition studies are then carried out by the in situ quartz crystal microgravimetry (QCM) technique. An Optimized Process is performed and compared to the classical Zn(S,O,OH) deposition. The morphology and composition of Zn(S,O,OH) films are determined using SEM and XPS techniques. The Optimized Process is tested on electrodeposited-CIS and co-evaporated-CIGSe absorbers and cells are completed with (Zn,Mg)O/ZnO:Al windows layers. Efficiencies similar or even better than CBD CdS/i-ZnO reference buffer layers are obtained (15·7% for CIGSe and 8·1% for (ED)-CIS). Copyright © 2009 John Wiley & Sons, Ltd.

low carbon high efficiency and sustainable production of traditional manufacturing methods through Process design strategy improvement Process for sand casting defects
Journal of Cleaner Production, 2020Co-Authors: Ju Zheng, Xingjia Zhou, Wei LingAbstract:Abstract Energy saving and emission reduction in traditional manufacturing can be achieved by reducing the occurrence of defective products. Most of the existing optimization methods are obtained by referring to production experience and technical manual, which are time-consuming and laborious. Thus, a method of Process selection and optimization for defective products in the design phase is required. In this paper, a Process design strategy based on design parameters for eliminating sand casting defects is proposed. Firstly, the technological Process and hole-type defects of sand casting are analyzed. The Process design parameters are divided into three categories to propose a Process design strategy. Three specific optimization schemes named OSP (structure parameters Optimized Process), OGP (gating system parameters Optimized Process), and OPP (Processing parameters Optimized Process) are derived. Then a carbon emission prediction model is established to evaluate the effect of these schemes, and a sustainable manufacturing evaluation method with six indicators is also raised. Finally, a case study illustrates that 21%–24% of Process carbon emission was saved after optimization on average. Among the strategies, OSP has the best energy-saving performance of average carbon emission, which is 4% lower than the others. OGP has the largest proportion of recyclable resources while OPP has the highest Process yield and lowest adjustment cost. The results show that the proposed strategies can effectively improve the Process yield, quality of casting, and decrease carbon emissions. The strategy raised in the paper supports the sustainable development of traditional manufacturing methods.
