  1. 16. 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

  3. 17. Novel Hybrid Nanomaterials : Combining Mesoporous Magnesium Carbonate with Metal-Organic Frameworks

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Viktor Sanderyd; [2018]

    Sammanfattning : Nanotechnology as a field has the potential to answer some of the major challenges that mankind faces in regards to environmental sustainability, energy generation and health care. Though, solutions to these concerns can not necessarily rely on our current knowhow. LÄS MER

  4. 18. Point source carbon capture by porous inorganic carbonates

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Jonas Hultberg; [2018]
    Nyckelord :Carbon capture; Gas separation; Adsorbent; Inorganic carbonates; Point source; Carbon dioxide; Kolavskiljning; Adsorbenter; Oorganiska karbonater; Punktkälla; Koldioxid;

    Sammanfattning : Mesoporous inorganic carbonates (MIC) was synthesized and tested as adsorbents for CO2, using vacuum and temperature swing adsorption. Mesoporous magnesium carbonate (MMC), mesoporous calcium carbonate (MCC) and mesoporous calcium magnesium carbonate (MCMC), all included in MIC, are exceedingly porous with an amorphous structure.

  5. 19. Investigation of Bismuth Iodine as Light Absorbing Materials for Solar Cell Applications: From Synthesis to XPS Characterisation

    Master-uppsats, Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Författare :Jonatan Fast; [2017]
    Nyckelord :Bismuth; Iodine; Light absorbing; Light absorbing materials; Solar; solar cell; Synthesis; XPS; Characterisation; synchrotron; energy; x-ray photoelectron spectroscopy; perovskite;

    Sammanfattning : During the last years perovskite materials have taken the photovoltaic community by storm, bringing promises of solar cells with efficiencies comparable to conventional silicon devices but at a lower price. However perovskite solar cells so far are facing two main obstacles, they are unstable in the presence of air, moisture and heat and they are usually toxic due to being based on lead-halide materials.

  7. 20. Using Upsalite® as drug delivery vehicle : Increasing the solubility of poorly soluble drugs by stabilizing their amorphous state

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för farmaci

    Författare :Ottilia Arvén; [2017]
    Nyckelord :;

    Sammanfattning : Poor aqueous solubility is an issue not only in drug discovery and development but also for registered drug products, since poor drug solubility is often related to poor absorption (bioavailability). There are several methods available to increase the aqueous solubility and dissolution rate of pharmaceutical formulations. LÄS MER
