      Spray-Processing Photovoltaics—A Coating For All: The cover image illustrates the first example of an organic photovoltaic device that is fully fabricated by spray coating onto a transparent conductive oxide. The goal has been reached by using an automated, compact apparatus able to perform spray processes in air. The Full Paper from Andrea Reale and colleagues on page 757 details the technological steps adopted at the Center for Hybrid and Organic Solar Energy (CHOSE) of University of Rome “Tor Vergata” and shows the appealing electrical results of the devices. Fully sprayed modules open the way to expand the application of photovoltaics to almost anywhere, thanks to the conformability of spray coating to virtually any kind of substrate. By addint the property of semitransparency, the range of possible applications gets even broader, from building-integrated photovoltaics to automotive or consumer electronics.

      “Aluminating” Results in Hydrogen Production: Hydrogen production from the hydrolysis of an Al/Al2O3 composite is described in the Full Paper on page 751 by Zhi Chen and Y. Huang with colleagues at China Jiliang University. The factors influencing the hydrolysis reactivity of aluminum are identified. A gel-coating processing method was used to prepare the Al/Al2O3-composite precursor powder. The reactivity and stability of the hydrolysis reaction on the heat-treated sample and Al/Al2O3 composite were investigated. The results indicate that the heat treatment is the predominant factor for the enhancement of reactivity whereas the addition of γ-Al2O3 decreases the hydrolysis reactivity, which is in contrast to previous reports. However, the addition of γ-Al2O3 has been shown to increase the stability of Al/Al2O3 in air.

      Novel Strategy! A strategy for the synthesis of porous hard carbons through a simple one-step thermolysis of conjugated microporous polymer (CMP) precursors for the use as anode materials for lithium ion batteries is presented. The CMP-derived porous hard carbons show desirable porous structure and large specific surface areas and exhibit a high reversible specific capacity, high rate performance, and long cycling life as anode materials.

      Waste cooking oil as an engine fuel! Alternative, renewable sources for fuels must replace fossil fuels in the next few decades. Waste-cooking-oil biodiesel has great potential to be widely used as a fuel for diesel engines. This study experimentally evaluates engine performance, combustion characteristics, and emissions for using waste-cooking-oil biodiesel as an alternative to conventional diesel fuel.

      Catalyzing success: Modified Zr–Mo-oxide catalysts were prepared by a facile and low-cost synthesis procedure and exhibited excellent catalytic activity and reusability in the esterification reaction, reacting oleic acid with methanol. This catalyst shows high promise for use in the future production of biofuels.

    3. Studying Catalyst Activity in an Isomerization Plant to Upgrade the Octane Number of Gasoline by Using a Hybrid Artificial-Neural-Network Model (pages 743–750)

      Hybrid Model: A hybrid-decay-function artificial neural network with recurrent layers (14 and 5 neurons in the input and output layers, respectively) was developed for an industrial light naphtha isomerization plant. Using these achievements, it is possible to monitor the activity of the catalyst and simulate the behavior of the industrial process, which is important for upgrading the octane level of gasoline.

    4. Hydrogen Generation by Hydrolysis of an Al/Al2O3-Composite Powder After Heat Treatment (pages 751–756)

      Xiani Huang, Zhi Chen, Tong Gao, Qiaoli Huang, Feng Niu, Laishun Qin and Yuexiang Huang

      Article first published online: 2 DEC 2013 | DOI: 10.1002/ente.201300129

      Composite results: An Al/Al2O3-composite powder is processed by using a gel-coating method, and heat treatment is shown to be the key point in improving Al-hydrolysis reactivity. The addition of Al2O3 deteriorates the hydrolysis reactivity of Al with water, however, it improves the stability of Al in air.

      A coating for all: Fully spray-processed photovoltaic modules represent an appealing result that opens the way to widespread use of photovoltaics, because spray coating can conform to virtually any kind of substrate. Here, the design of an automated spray-coating process is demonstrated, completely performed in air, to fabricate the first fully spray-coated modules on glass/transparent-conducting-oxide (TCO) substrates.

      Living with uncertainty? Photovoltaic modules presently manufactured in the solar industry are typically rated with ±5 % tolerance in maximum power. In this study, the sources of uncertainty in sun-simulator power measurements are analyzed and it is found that even class A solar simulators can have high uncertainties in measurement, especially in irradiance over the test area, which can affect the final results.

    7. Screen-Display-Induced Photoresponse Mapping for Large-Area Photovoltaics (pages 770–775)

      Ritu Gupta, S. Kiruthika, K. D. M. Rao, Dr.  M. Jørgensen, Prof.  F. C. Krebs and Prof.  G. U. Kulkarni

      Article first published online: 5 DEC 2013 | DOI: 10.1002/ente.201300154

      Reducing labor: Areal examination of the solar cell performance is made possible by placing the device onto a dark computer screen as a light spot is raster scanned across the cell to generate a local photoresponse. The screen-display-induced photoresponse map gives a pictorial view of the degraded and damaged areas in addition to providing an insight into interfacial defects.
