  1. 11. Study of luminescent and energy properties of CsPbBr3 and CsPbI3 nanoplatelets

    L3-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Taddeo Salique; [2022]
    Nyckelord :quantum confinement; nanoplatelets; CsPbBr3; CsPbI3; semiconductor; exciton; perovskite nanocrystals;

    Sammanfattning : Halide perovskite semiconductor nanocrystals have been studied a lot recently because they allow a precise control over the entire visible emission spectrum and as a result, the possibility of a variety of light-emitting applications. In this study, cesium lead bromide CsPbBr3 and cesium lead iodide CsPbI3 nanoplatelets of 3, 4 and 5 monolayers (ML) have been synthesized. LÄS MER

    Sammanfattning : Primitive magmas can provide important details about the mantle from which they are derived. In this thesis, petrographic observations and new mineral chemistry analyses of the Sälskär breccia from the Alnö alkaline complex, central Sweden, are reported. LÄS MER

  5. 14. Carbon-coated Lead Halide Perovskite Quantum Dots and Copper(I)Iodide Coated Copper Nanowire Electrodes for Flexible Solar Cells

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Albin Andersson; [2022]
    Nyckelord :Nanotechnology; solar cells; perovskite; quantum dots; nanowire; thin film electrodes; nanoteknologi; solceller; perovskit; kvantprickar; nanotrådar;

    Sammanfattning : Lead Halide Perovskite is emerging quickly as a promising material for the future solar cellsthanks to their inherent good optoelectrical properties along with their cheap and facile fabri-cation. However, their main drawback before commercialization is their weak stability. LÄS MER

  7. 15. Characterization of as prepared and exposed Perovskitesolar cells by microscopic and spectroscopic techniques

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Nagaraju Gorella; [2021]
    Nyckelord :Perovskites; Solar Cell; SEM; AFM; c-AFM; Photoluminescence; Electroluminescence; Solar simulator.;

    Sammanfattning : Studying the microstructural features, optical, and electrical properties of the thin-filmperovskite solar cells (PSC) is the main objective of this thesis work. All the PSCs used in thisthesis work were prepared by spin coating assisted with gas quenching process and the samplesreceived from Interuniversity Microelectronics Centre (IMEC), Belgium. LÄS MER
