  1. 1. InP/GaInP Nanowires for Tandem Junction Solar Cells : Growth, Processing, and Characterization

    Författare :Xulu Zeng; Fasta tillståndets fysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanowires; GaInP; InP; tandem; tunnel diode; solar cell;

    Sammanfattning : Semiconductor nanowire solar cells have achieved comparable efficiency to their planar counterparts with substantial reduction of material consumption. Tandem geometry is a path towards even higher efficiency. However, extensive studies are needed to reach this goal. LÄS MER

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

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

    Sammanfattning : 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.

  4. 3. Light Trapping and Alternative Electrodes for Organic Photovoltaic Devices

    Författare :Kristofer Tvingstedt; Olle Inganäs; Peter Peumans; Linköpings universitet; []
    Nyckelord :Light trapping; Organic solar cells; Tandem cells; Polymer solar cells; Plastsolceller; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Organic materials, such as conjugated polymers, have emerged as a promising alternative for the production of inexpensive and flexible photovoltaic cells. As conjugated polymers are soluble, liquid based printing techniques enable production on large scale to a price much lower than that for inorganic based solar cells. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 5. Electron tomography and optical modelling for organic solar cells

    Författare :Viktor Andersson; Olle Inganäs; Joachim Loos; Linköpings universitet; []
    Nyckelord :Organic solar cells; Electron tomography; Optical modelling;

    Sammanfattning : Organic solar cells using carbon based materials have the potential to deliver cheap solar electricity. The aim is to be able to produce solar cells with common printing techniques on flexible substrates, and as organic materials can be made soluble in various solvents, they are well adapted to such techniques.
