  2. 1. Materials Development for Solid-State Dye-Sensitized Solar Cells

    Author : Martin Karlsson; Anders Hagfeldt; Gerrit Boschloo; Lukas Schmidt-Mende; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The dye-sensitized solar cell (DSC) is a photovoltaic technology with the potential to efficiently and economically harvest and convert energy from the sun to electrical power. DSCs are built using abundant and low cost materials such as titanium dioxide (TiO2) and organic dye molecules. READ MORE

  4. 2. Designing and Tuning the Properties of Materials by Quantum Mechanical Calculations

    Author : Jailton Souza de Almeida; Rajeev Ahuja; Patrizia Monachesi; Uppsala universitet; []
    Keywords : Physics; Density Functional Theory; Electronic Structure; Phase Transitions; High Pressure; Optical Properties; Dielectric Functions; Semiconductors; Metals; Fysik;

    Abstract : In many materials, changes in chemical composition, pressure or temperature can induce metal to insulator transitions. It is recently observed in yttrium hydride, for example, changes from a shiny mirror (YH2) to a transparent window (YH3), which has important technological application in optical devices. READ MORE

  5. 3. Nanostructured Metal Oxide Semiconductors for Functional Applications

    Author : Anton Landström; Isabella Concina; Alberto Vomiero; Caterina Soldano; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics;

    Abstract : This thesis is about nanostructured metal oxides, their properties, and some of their applications. Semiconducting metal oxides like TiO2, ZnO,and SnO2 have a wide band gap, which means they absorb UV light andgenerate electron-hole pairs. READ MORE

  6. 4. High-Quality Perovskite Films for Efficient and Stable Light-Emitting Diodes

    Author : Heyong Wang; Feng Gao; Olle Inganäs; Xiaoke Liu; Ifor David William Samuel; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; perovskite light-emitting diodes; efficiency; stability; growth process; ion migration;

    Abstract : Metal halide perovskites have attracted significant attention for light-emitting applications, because of their excellent properties, such as high photoluminescence quantum yields (PLQYs), good charge mobility, narrow emission bandwidth, readily tunable emission spectra ranging from ultraviolet to near-infrared, and solution processability. Since the first room-temperature perovskite-based light-emitting diodes (PeLEDs) reported in 2014, tremendous efforts have been made to promote the efficiencies of PeLEDs, including theoretical simulation, materials design, and device engineering.

  7. 5. Charge Separation on Localized Surface Plasmon and Hot Carrier Transfer to Semiconductors

    Author : Yocefu Hattori; Jacinto Sá; Stephan Link; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasmonics; hot carrier; metal nanoparticles; semiconductors; ultrafast transient absorption spectroscopy; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Abstract : The relatively recent discovery that plasmonic nanoparticles generate energetic electron-hole pairs known as hot carriers has been the source of interest from many scientific groups. The capability to extract these short-lived hot carriers from metal nanoparticles (NPs) might potentially lead to applications in solar cells, photodetection, and photocatalysis. READ MORE
