  1. 1. Understanding interfaces in thin-film solar cells using photo electron spectroscopy. : Effect of post-deposition treatment on composition of the solar cell absorber.

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Henrik Hansson; [2019]
    Nyckelord :solar cell; P-N junction; CIGS; PES; cross section;

    Sammanfattning : The increasing demand of renewable energy is the big driving force for the research and development of more efficient solar energy conversion solutions. Solar cells, which use the photovoltaic effect to convert the photon energy to electrical current, are an important solar energy conversion technique. LÄS MER

  3. 2. Experimental and theoretical studies of water droplet surfaces in the presence of glycerol

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Nygren Anton; [2017]
    Nyckelord :glycerol; water surface; BESSY II; MD; GROMACS; PES; XPS; glycerol; vattenytor; BESSY II; MD; GROMACS; PES; XPS;

    Sammanfattning : Water aerosols affect the climate because they have an impact on the radiation balance and cloud formation. Water is present in all forms in the atmosphere (water, ice and steam), for example as rain and hail. Water aerosols play an important role in many biological and chemical processes in the atmosphere. LÄS MER

  4. 3. Simulations of a Ruthenium Complex and the Iodide/Triiodide Redox Couple in Aqueous Solution: Solvation and Electronic Structure

    Magister-uppsats, Institutionen för fysik och astronomi

    Författare :Ida Josefsson; [2010]
    Nyckelord :Dye-sensitized solar cells; molecular modeling; quantum chemistry; molecular dynamics; photoelectron spectroscopy; Färgämnessensiterade solceller; molekylmodellering; kvantkemi; molekyldynamik; fotoelektronspektroskopi;

    Sammanfattning : In dye-sensitized solar cells, the functions of light absorption and charge transport are separated. A photosensitive ruthenium-polypyridine dye in the cell absorbs light, injects an electron to a semiconductor and is then regenerated by a redox couple, typically iodide/triiodide. LÄS MER
