  1. 1. Analys av platinaytor och platinatennytor under katalytisk etanoloxidation med röntgenfotoelektronspectroskopi

    Magister-uppsats, Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Författare :Mats Viktor Löfstrand; [2023]
    Nyckelord :Pt3Sn; APXPS; Ethanol oxidation; Pt 111 ; Pt 223 ;

    Sammanfattning : Fuel cells are more efficient and cleaner than combustion engines. Ethanol as a fuel has a high energy density and is safer and easier to handle than hydrogen which is normally used in fuel cells. If efficient fuel cells on alcohol were available, they could be used for engines and power sources for electronics. LÄS MER

  3. 2. Study of solution-based Cs0.1FA0.9Pb(I0.9Br0.1)3 perovskite deposition with scalable technology for solar cell production : Characterization of optical properties and function of the solar cell

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fysikalisk kemi

    Författare :Tasnim Laskar; [2021]
    Nyckelord :;

    Sammanfattning : Climate change is one of the greatest challenges of the 21st century and is the reason for several environmental changes on earth. One reason behind climate change includes the rise ingreenhouse gas emissions in the atmosphere due to the burning of coal, gas and oil, i.e. fossil fuels. LÄS MER

  4. 3. Film formation of mixed-halide perovskites for PSCs

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Lina Ekstedt; [2021]
    Nyckelord :Mixed Halide Perovskites; Perovskite Solar Cells; Bandgap Tuning; In-situ Spectroscopy; Antisolvent; Interface Modifier.; Physics and Astronomy;

    Sammanfattning : Over the last few years there has been a steady increase in interest in the exploration of perovskite materials within photovoltaic research. This can to a large extent be attributed to the incredible pace at which solar cells based on perovskites have improved in efficiency during the same time period. LÄS MER

  5. 4. Intermediate layer contacts for tandem solar cells based on ALD SnO2

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

    Författare :Georgia Iona; [2021]
    Nyckelord :Ald; SnO2; tandem cell; solar cell; IML; intermediate layer;

    Sammanfattning : In this project, samples with a metal/semiconductor/metal structure were fabricated and investigated with the potential application as the interconnecting layer of a tandem solar cell in mind. Degenerately doped p-Si and n-Si were used as bottom (metal like) contacts, as Si represents one of the most common materials for the bottom cell of tandem devices. LÄS MER

  7. 5. Effects of the interfaces in planar hybrid lead trihalide perovskite solar cells with n-type and p-type inorganic charge transport layers

    Master-uppsats, KTH/Energiteknik

    Författare :Olivier Jaques Henri Fournier; [2018]
    Nyckelord :;

    Sammanfattning : Perovskite-solceller är en framväxande och lovande tunnfilmsteknik, som uppnådde hög effektivitet på en ofantlig kort tid. Den nuvarande arkitekturen i cellen, som innefattar titanoxid och Spiro-OMeTAD (en organisk förening) som laddningstransportlager (CTL), saknar stabilitet och visar hysteretiskt beteende. LÄS MER
