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

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

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

    Abstract : 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. READ MORE

  3. 17. Nano-Graphene Oxide Surface-Functionalized Poly(e-caprolactone) Scaffolds with Drug Delivery Capability

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Yao Jenevieve Linell; [2018]
    Keywords : Poly e-caprolactone PCL ; aminolysis; graphene oxide; tissue scaffolds; ciprofloxacin;

    Abstract : Grafenoxid (GO) ar en lovande kandidat som nano-tillsats i medicinska byggnadsstallningar for benregenerering. GO kan forbattra den biologiska kompatibiliteten och osteogena prestandan hos polymerbaserade byggstallningar, och ocksa vasentligt bidra till forbattringen av materialets mekaniska egenskaper.

  4. 18. Investigation of growth modes of the lithoautotrophic bacterium Cupriavidus necator

    University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Author : Raquel Perruca Foncillas; [2018]
    Keywords : applied microbiology; teknisk mikrobiologi; Technology and Engineering;

    Abstract : The microorganism Cupriavidus necator is a very interesting bacterium that has been established as a model microorganism for its capability to produce polyhydroxyalkanoates, more specifically polyhydroxybutyrate (PHB), a potential precursor/raw material for bioplastics. Lately, the scientific community has raised interest in the chemolithoautotrophic nature of C. READ MORE

  5. 19. Optical spectroscopy of impurity atoms in semiconducting Nanowires

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Shishir Shroff; [2017]
    Keywords : Photoluminescence; Nanowire; Defects; Diffusion; GaAs; Copper; Physics and Astronomy;

    Abstract : In a small and confined one dimensional geometry of nanowire, even few defects can influence the performance of the devices. Main objective of this thesis is to conduct photoluminescence study of such defect states in GaAs nanowires, which we will first introduce by diffusing copper impurity atoms, in very low concentrations.

  6. 20. DFT investigations of the donor-acceptor couple CuPc/C60

    University essay from Uppsala universitet/Materialteori

    Author : Pamela Svensson; [2016]
    Keywords : DFT; donor; acceptor; couple; CuPc; C60; XPS; XES; NEXAFS; spectroscopy; organic; solar; cell; buckminsterfullerene; copper; phthalocyanine; blue;

    Abstract : The donor-acceptor couple CuPc/C60 has been the subject of recent studies in organic solar cells due to its combined abilities in light absorption (CuPc) and charge transport (C60). By better understanding the electronic and geometric nature of the system it is possible to shed light on how the molecules act under different conditions. READ MORE
