  1. 1. Spectroscopy on the Dot : Photoelectron Spectroscopy and Time-Resolved Studies of Lead Sulfide Quantum Dots for Solar Cells

    Författare :Tamara Sloboda; Ute B. Cappel; Andreas Lindblad; Lars Kloo; Regan Wilks; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry;

    Sammanfattning : Renewable energy is an important topic as global energy consumption continues to rise. Because the sun emits an enormous amount of energy, solar energy is a promising source. However, most of the commercial solar cell technology is manufactured in an energy demanding process and there is a need for new, easily processed materials. LÄS MER

  3. 2. The life and death of perovskites : Interfacial function and degradation of lead halide perovskites studied by photoelectron spectroscopy

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lead halide perovskite solar cells; interfacial degradation; heterojunction interfaces; photoelectron spectroscopy; operando; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : Lead halide perovskite solar cells are a promising new technology which could soon see widespread commercial application but is partly held back by poor long-term stability. In this thesis, photoelectron spectroscopy (PES) is used to study the dynamical processes at the surface or interfaces of lead halide perovskite materials. LÄS MER
