The Al–Mg electrodeposition is investigated using the organometallic–based electrolyte: Na[AlEt4]+2Na[Et3Al–H–AlEt3]+2.5AlEt3+6toluene (Et =-C2H5), employing Mg anode. With an increase of Mg in the deposit the predominant morphology and its composition changes from ground (90–95 atom% Al) to smooth globules (75–80 atom% Al) to rough globules (15–45 atom% Al). The ground and smooth globules possessed face centered cubic (fcc) Al(+Mg) phase and the rough globules possess hexagonal close packed (hcp) Mg(+Al) phase. The overall composition (atom% Al-the more noble metal) of the deposits is less than that of the electrolyte, and increases steeply with a slight change in the latter. This indicates the absence of preferred deposition of the more noble metal suggesting the anomalous electrodeposition of Al-Mg. A critical ratio of Al/Mg exists in the electrolyte beyond which the anomalousness is enhanced. This critical ratio is identified by the onset of hcp Mg(+Al) phase formation in the deposits. A lack of trend in the overall deposit composition with electrolyte agitation affirms the anomalous electrodeposition of Al–Mg system under present experimental conditions.

“…The former process has been proposed for the electrodeposition of CdS [61] , CdSe and Ag 2 S [62] , CdTe [63] , CuInSe 2 [64] , and Sb 2 S 3 [65] . The latter process has been proposed for the cathodic deposition of Ni 3 S 2 from a nickel thiosulfate solution [66] : The two different cathodic deposition processes can be differentiated by studying the current effi ciency of deposition and the secondary products formed in solution [67] . The Pourbaix diagrams for CdS, CdTe, CuInSe 2 , CdSe, and Sb 2 S 3 based on thermodynamic considerations (Figures 5.5 -5.9 respectively) show clearly that the voltage -pH region where stability of the corresponding materials can be obtained is very limited.…”

IntroductionThe world net electricity generation has been estimated to increase 77% from 18 trillion kilowatt hour s ( kWh ) in 2006 to 31.8 trillion kWh in 2030 with a value of 23.2 trillion kWh in 2015 1) . On the other hand, the world market capacity of solar photovoltaic power systems escalated from 1.3 gigawatt s ( GW ) in 2001 to 15.2 GW in 2008 for systems which have been installed. In particular, market installations reached a record high of 5.95 GW in 2008 corresponding to a growth of 110% from 2007. The contribution of solar energy to the world net electricity generation is estimated to be 6% by 2050.The production of photovoltaic ( PV ) modules is still based mainly on crystalline silicon (Si) (94%) while 4% of modules are based on thin -fi lm amorphous Si solar cells and 2% are polycrystalline compound solar cells based on CdTe and CuIn 2 Se [1] . Despite the tremendous progress in all aspects of production of Si -based solar cells and the rapid decrease of production cost for PV modules from $5 per peak watt at the beginning of the 1990s to $2.5 per peak watt in 2009, or $0.7 per kWh, this remains effectively too high. Subsidies from some government policies and/or the carbon dioxide market to increase the utilization of clean energy for sustainable development can contribute to reduce the PV energy cost to $0.25 -0.40 per kWh during the fi rst year of the system installation. This cost is similar to that of classic energy where energy cost is higher than $0.25 -0.30 per kWh. For economic viability of this energy without subsidies, the development of ultralow -cost PV systems is one of the important issues to ensure a smooth transition to sustainable energy development. According to a recent US Department of Energy study in the USA [2] , a major research effort is needed to close the huge gap between the current use of solar energy and its enormous underdeveloped potential. One of the identifi ed thrusts of the 5 Advances in Electrochemical Science and Engineering. Edited
