  1. 6. Advanced silicon photoelectrodes for water splitting devices : design, preparation and functional characterization by photo-electrochemistry and high-energy X-ray spectroscopy

    Författare :Anurag Y. Kawde; Johannes Messinger; Pieter Glatzel; Thomas Jaramillo; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photoelectrochemical cell; photoelectrodes; solar-water splitting; artificial photosynthesis; X-ray absorption and emission spectroscopy;

    Sammanfattning : For the last century, mankind has been hugely dependent on fossil fuels to meet its energy needs. Harnessing energy from fossil fuels led to the emission of greenhouse gases. Greenhouse gases such as CO2 are a major contributor to global warming. LÄS MER

  3. 7. Norbornadienes for molecular solar thermal energy storage

    Författare :Maria Quant; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; energy storage; solar energy; norbornadiene - quadricyclane photo switches; synthesis of norbornadienes.;

    Sammanfattning : Over the last decade, there has been great scientific progress in terms of harvesting solar energy but the area of storing energy is still facing challenges. One approach to store solar energy is via photoinduced isomerization of chemical bonds, referred to as molecular solar thermal energy storage (MOST). LÄS MER

  4. 8. Theoretical Studies on Artificial Water Splitting-Water Oxidation and Proton Transfer

    Författare :Ying Wang; Hans Ågren; James Gardner; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The present thesis is concerned with the theoretical studies on artificial water splitting process. As the quick development of research on utilizing of solar energy, which is a green, clean, and renewable energy source, many research groups focus their attention on artificial photo-synthesis systems inspired by the photosystem I and II.
