  2. 1. Development of Nanoparticle Sensitized Solar Cells

    Author : Chunze Yuan; Hans Ågren; Anders Hagfeldt; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum dots; quantum rods; nanoparticles; solar cells; colloidal; type-II; electron extraction; alloy; organic electrolyte; energy relay; upconversion.;

    Abstract : In this thesis, I have been working with the development of nanoparticle sensitized solar cells. In the subarea of quantum dot sensitized solar cells (QDSCs), I have investigated type-II quantum dots (QDs), quantum rods (QRs) and alloy QDs, and developed novel redox couples as electrolytes.

  4. 2. Functional Metal Oxide Materials Deposited by Inkjet Printing Technique

    Author : Yan Wu; Lyubov Belova; Gillian Gehring; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inkjet printing; photoconductivity; ZnO; Al-ZnO; composite; electron transfer; CdS; field effect transistor; photosensitive; RT do-ferromagnetism; Mn-doped ZnO; MgO; Materials science; Teknisk materialvetenskap;

    Abstract : This thesis presents a comprehensive study of the intrinsic room temperature ferromagnetism in 85 to 100nm thin films produced by in situ deposition of industrially important pristine MgO and ZnO by inkjet printing. It is suggested that the observed long range magnetic order, the so-called do magnetism in these oxides arises from cation vacancies. READ MORE

  5. 3. Optical Properties of Nanoparticles in Composite Materials

    Author : Lin Dong; Sergei Popov; Ari Friberg; Toralf Scharf; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Nanoparticles are synthetic structures with dimension from 1 to 100 nanometers and are various in types. Some favorable properties peculiar to the nanoparticles (generally owing to size effects) make them prevailing and beneficial for applications in different scientific and engineering fields.
