  1. 1. Investigating the potential dependence of the apparent diffusivity of lateral self-exchange on mesoporous ZrO2 film

    Kandidat-uppsats, Uppsala universitet/Institutionen för kemi - BMC

    Författare :Paul Wefer; [2023]
    Nyckelord :Lateral self-exchange; mesoporous film; D35; spectroelectrochemistry;

    Sammanfattning : Lateral self-exchange of charge across dye-sensitized film is a phenomenon that may play animportant role in effectivizing H2 production from water via solar energy, and shows potential forother interesting applications. The rate of charge movement via lateral self-exchange across afilm is often quantified in terms of apparent diffusivity of charge, Dapp. LÄS MER

  3. 2. Design, synthesis and characterization of Dimethylammonium / Ethylammonium / Cesium Lead  Halide Perovskites for optoelectronic applications

    Kandidat-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Elin Ljungström; Ellen Hådén; Lukas Lekberg; Nima Taherpour; [2020]
    Nyckelord :Perovskit; solcell; perovskitsolcell; halvledare; organiska oorganiska perovskiter;

    Sammanfattning : The world is facing a climate crisis and to be able to solve it society needs to decrease the use of fossil fuels and find renewable alternatives. Solar energy is a great contender for a renewable energy source since it can be harvested for eternal time. LÄS MER

  4. 3. Medical Implant Applications of Mesoporous Silica Films

    Kandidat-uppsats, Linköpings universitet/Nanostrukturerade material

    Författare :Patrik Geite; [2019]
    Nyckelord :Mesoporous silica; films; implants; drug delivery; osseointegration;

    Sammanfattning : A literature review of medical implant applications of mesoporous silica films was written, highlighting the advantages and limitations of different film synthesis methods. Both films synthesized through the EISA sol-gel method and particulate films, including those synthesized through the direct growth method, were reviewed and discussed. LÄS MER

  5. 4. SnOx electron selective layers for perovskite/silicon tandem solar cells using atomic layer deposition

    Master-uppsats, KTH/Energiteknik

    Författare :Lisa Anna Zafoschnig; [2018]
    Nyckelord :;

    Sammanfattning : In this work the application of ALD deposited SnOx films as electron transport layers in perovskite solar cells is analysed. Processes to fabricate homogeneous, transparent and conductive tin oxide films were developed on an Oxford Instruments FlexAL tool using a TDMASn precursor and H2O as oxidiser. LÄS MER

  7. 5. Syntes och karakterisering av ogiftiga organiska metall halid halvledare för solceller

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Oskar Dahlin; [2015]
    Nyckelord :Solar cells; Solar energy; Lead free perovskites; Semiconductors; Organic metal halide;

    Sammanfattning : The endeavor to have more efficient solar cells and as environmentally beneficial as possible are the driving forces for this work. The way to reach this is by research to better the understanding of the mechanisms and parameters that govern the performance of solar cells. LÄS MER
