  2. 1. Composite Nanostructured Materials for Renewable Energy Applications

    Author : Elfatih Mohammed Mustafa; Omer Nur; Magnus Willander; Malik Maaza; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar energy; Photocatalysis; Solar cells; Nanostructured materials; ZnO; CuO; Ta2O5; GaAs;

    Abstract : Diverse sources of energy are becoming increasingly significant in today's world. The most common source of energy today is fossil fuels, such as coal, oil, and gas. While this energy source has many advantages, it also comes with many problems. READ MORE

  4. 2. A molecular guide to efficient charge transport : Coordination materials for photovoltaic cells

    Author : Hannes Michaels; Marina Freitag; Aldo Di Carlo; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coordination chemistry; energy conversion; photovoltaics; charge transport;

    Abstract : Emerging solar energy conversion and energy storage technologies play a vital role in solving the present energy crisis and achieving carbon net zero. Currently, they are limited by the use of inefficient, unstable and expensive charge transport materials. READ MORE

  5. 3. Discovering Hidden Traps : in Nickel Oxide Nanoparticles for Dye-Sensitised Photocathodes

    Author : Luca D'Amario; Leif Hammarström; James Durrant; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The finite nature of fossil fuels and their effect on the global climate, raised the need to find an alternative source of energy. This source should be environment compatible, cheap and abundant. The light coming from the Sun is a promising alternative. READ MORE

  6. 4. Photophysics and Photochemistry of Iron Carbene Complexes

    Author : Linnea Lindh; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tidsupplöst spektroskopi; täthetsfunktionalteori; järn-komplex; färgämne; grätzelsolcell; fotokatalys; elektronöverföringsreaktion; time-resolved spectroscopy; density functional theory; earth-abundant; iron-complex; photosensitiser; dye-sensitised solar cell; photocatalysis; electron transfer;

    Abstract : Nature captures sunlight via light-absorbing molecules.Similarly, photosensitisers are used in applications of solar cells and artificial photosynthesis to absorb sunlight, and transfer the excited electron. READ MORE

  7. 5. Dyes and their adsorption onto nanocrystalline TiO2 electrodes : Synthesis, characterisation and applications

    Author : Viviane Aranyos; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi; organisk kemi; Organic Chemistry;

    Abstract : The syntheses of two type of dyes (phthalocyanine and ruthenium tris-bipyridyl) are presented here. Their characterisation involves the use of cyclic voltammetry, NMR- and UV-visible spectroscopy. Once adsorbed on nanocrystalline TiO2 electrodes, their electrochemical, spectroelectrochemical and photoelectrochemical properties were investigated. READ MORE
