  1. 6. Mätutrustning för Solcellers Responstid : En Undersökning i Analog Elektronik

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Vilgot Samuelsson; Axel Algeroth von Thiele; [2023]
    Nyckelord :elektronik; analog; mätinstrument; solceller; responstid; perovskit; transimpedans; arduino; platformIO; optoelektronik; kretskort;

    Sammanfattning : Perovskite solar cells (PSCs) have shown great potential for the future of solar powered energy production. They are however not completely flawless, and one of their more disadvantageous properties are their relatively slow response time. LÄS MER

  3. 7. Surface orientation of the formamidinium cation in black formamidinium lead iodide perovskite

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Torsten Geirsson; [2023]
    Nyckelord :Perovskite; Formamidinium; Surface;

    Sammanfattning : Formamidinium lead iodide perovskite (FAPI) holds promise to be used in high–efficiency solar cells. A comprehensive understanding of the immediate surface properties of this material can provide insights into its interaction with other materials and guide future engineering of its interface with other constituents of the solar cell.

  4. 8. In situ X-ray diffraction studies of vertically aligned CsPbBr3 nanowire arrays

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Jesper Larsson; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The past decade has seen a great interest in the development of metal halide perovskite materials for use in photo-optical devices, due to the excellent photo-optical properties of these materials. The primary limitation to industrial adoption, and the subject of much research, is the susceptibility of these materials to degradation from exposure to various factors such as air, heat and moisture.

  5. 9. X-Ray Fluorescence of Metal Halide Perovskites

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Samuel Narciso Silva; [2022]
    Nyckelord :Perovskite; X-ray; Fluorescence; Python; PyMCA; Synchrotron radiation; Physics and Astronomy;

    Sammanfattning : This thesis has the aim to provide a framework for analyzing X-ray fluorescence (XRF) data obtained from German Electron-Synchrotron Group (DESY). The theoretical analysis shows that XRF competes with Auger emission, and works mainly for elements with high atomic number. Here, incident X-rays of 13. LÄS MER

  7. 10. Reaction of Copper and Copper(I) Iodide with Iodine and Strong Field Ligands

    Master-uppsats, KTH/Tillämpad fysikalisk kemi

    Författare :Aya Ali; [2022]
    Nyckelord :in films; AFM; copper iodide; solar cells; transparent conductive films; tunnfilm; AFM; koppar jodid; solceller; transparent ledande film;

    Sammanfattning : Perovskit solceller (PSCs) är kända som 'ljusomvandling' enheter med ökad omvandlingseffektivitiet (PCE). PSCs är kända för detta flexibilitet och hög tolerans mot defekter och består av fem lager med olika material och egenskaper. LÄS MER
