  1. 16. Processing techniques of perovskite solar cells : Properties depending on material and manufacturing

    University essay from Uppsala universitet/Fysikalisk kemi

    Author : Andréa Nordmark; Simon Nilsson; [2023]
    Keywords : ;

    Abstract : This project investigates how different types of perovskite solar cells, differentiated by choice of materials and processing techniques, compares to each other regarding performance and characterization. The purpose of the project is to further develop perovskite solar cells and to improve the method of manufacturing for better performance. READ MORE

  3. 17. Operando detection of Li-plating by online gas analysis and acoustic emission monitoring

    University essay from Uppsala universitet/Strukturkemi

    Author : Inti Espinoza Ramos; [2023]
    Keywords : Li-ion batteries; graphite; solid electrolyte interphase; lithium plating; online gas analysis; operando acoustic emission monitoring;

    Abstract : Lithium ion batteries (LIBs) are widely used for storing and converting chemical energy into electrical energy. During battery operation, lithium ions move between electrode materials, enabling energy storage. However, aging mechanisms like lithium plating can negatively impact battery performance and lifetime. READ MORE

  4. 18. Impact of nanoparticle plasmons on photoluminescense and upconversion processes in ZnO

    University essay from Uppsala universitet/Solcellsteknik; Uppsala universitet/Fysikalisk kemi

    Author : Axel Gudmundsson; [2023]
    Keywords : Photoluminescence; Upconversion; Plasmons; ZnO;

    Abstract : The increasing prevalence of glass windows in modern buildings has raised the demand for solar control windows that possess climate-appropriate properties. Glass windows made of abundant and low-cost materials which can both decrease the heating energy consumption as well as enhance the light climate indoors would sufficiently meet the goals of economical yet uplifting buildings.

  5. 19. Chromia-Alumina Thin Films from Alkoxide Precursors : From Precursor Synthesis to Deposition and Characterisation

    University essay from Uppsala universitet/Oorganisk kemi

    Author : Elina Elvelo; [2023]
    Keywords : alkoxide; synthesis; thin film; coating; alumina; chromia; spinodal decomposition;

    Abstract : A hetero-bimetallic alkoxide CrAl3(OiPr)12 was synthesised through metathesis of achromium(III)chloride THF complex (CrCl3 . 3 THF) and 3 KAl(OiPr)4.It was used as a single sourceprecursor to make oxide powders and films with 1:3 chromium/aluminium compositionthrough sol-gel synthesis.

  6. 20. Flashlamp Annealing for Improved Ferroelectric Junctions

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Theodor Blom; [2023]
    Keywords : Flashlamp annealing; ferroelectricity; hafnia oxide; III-V semiconductor; thermal annealing; device performance; Technology and Engineering;

    Abstract : The effects of flashlamp annealing (FLA) on the quality of ferroelectric HfxZr1–xO2 (HZO) interfaces, integrated on InAs substrates, are evaluated. For the integration of ferroelectric HZO on III-V semiconductors the crystallization via rapid thermal processing (RTP) can severely degrade the HZO/III-V interface. READ MORE
