  1. 1. Electrolyte Semiconductor Combinations for Organic Electronic Devices

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Elias Said; Magnus Berggren; Xavier Crispin; Gilles Horowitz; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Electrochemistry; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik Elektrokemi;

    Abstract : The discovery of semi-conducting organic materials has opened new possibilities for electronic devices and systems because of their solution processibility, lightweight and flexibility compared to inorganic semiconductors. The combination of semiconductors with electrolytes, and more especially organic semiconductors and solid electrolytes has attracted the attention of researchers because of the multiple phenomena originating from the simultaneous motion of electrons and ions.

  2. 2. The anode and the electrolyte in the MCFC

    University dissertation from Stockholm : Kemiteknik

    Author : Andreas Bodén; Göran Lindbergh; Carina Lagergren; Takao Watanabe; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; composite electrolytes; electrode kinetics; nickel solubility; porous electrode; reformate; water-gas shift reaction; electrolyte; electrolyte distribution; hydrogen oxidation reaction; ion segregation; mass transport; mathematical modelling; MCFC; molten carbonate fuel cell; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik;

    Abstract : A goal of the Swedish government is to increase the usage of renewable fuels and biomass-based fuels. Fuel cells, and especially the MCFC, are useful for these types of fuels. The Swedish market may benefit from the MCFC in two ways: increased efficiency of the biofuels and also utilisation of produced heat in district heating. READ MORE

    Abstract : Nowadays lithium-ion batteries (LIBs) are the dominant power sources of portable electronic devices such as mobile phones, laptops and cameras. Although recently their applications have extended to areas of electromobility and hybridization of vehicle, cost and safety issues remain as big obstacles for a smoother implementation. READ MORE

  5. 5. Electrolyte-Based Dynamics: Fundamental Studies for Stable Liquid Dye-Sensitized Solar Cells

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Jiajia Gao; Lars Kloo; Elizabeth Gibson; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dye-sensitized solar cells; Stability; Electrolyte; Cobalt redox couples; Additives; Kemi; Chemistry;

    Abstract : The long-term outdoor durability of dye-sensitized solar cells (DSSCs) is still a challenging issue for the large-scale commercial application of this promising photovoltaic technique. In order to study the degradation mechanism of DSSCs, ageing tests under selected accelerating conditions were carried out. READ MORE
