  4. 2. Single Junction and Tandem Junction Nanowire Solar Cells

    Author : David Alcer; NanoLund: Centre for Nanoscience; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Nanowire solar cell; GaInP; InP; Tandem junction; Vertical processing;

    Abstract : Solar cells based on silicon are successfully harvesting solar energy in established and increasingly widespread solar panels. However, their efficiency is limited by the Shockley–Queisser limit. For certain applications where high efficiency is the key figure of merit, the use of multi-junction solar cells is desirable.

  6. 4. Measuring quantum systems with a tunnel junction

    Author : Joachim Wabnig; Jörgen Rammer; Ulrich Eckern; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum mechanics; quantum measurement; tunnel junction; qubit; nanomechanics; noise; Physics; Fysik;

    Abstract : This thesis is concerned with employing the statistics of charge transfer in a conductor as a tool for quantum measurement. The physical systems studied are electronic devices made by nanoscale manufacturing techniques. In this context quantum measurement appears not as a postulate, but as physical process. READ MORE

  7. 5. Growth and Characterization of Tandem-Junction Photovoltaic Nanowires

    Author : Lukas Hrachowina; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III–V semiconductors; nanowire; photovoltaics; tandem junction; MOVPE; EBIC; Fysicumarkivet A:2022:Hrachowina;

    Abstract : In order to satisfy the growing energy needs of our planet’s population, and at the same time mitigate global warming, sustainable energy sources such as solar energy are indispensable. In addition to conventional silicon-based solar cells, nanotechnology offers interesting approaches for complementary applications. READ MORE
