  1. 21. Organic-inorganic hybrid perovskites as light absorbing/hole conducting material in solar cells

    Uppsats för yrkesexamina på avancerad nivå, Fysikalisk kemi

    Författare :Saman Ghanavi; [2013]
    Nyckelord :;

    Sammanfattning : Solar cells involving two different perovskites were manufactured and analyzed. The perovskites were (CH3NH3)PbI3 and (CH3NH3)SnI3. Both perovskites have a shared methyl ammonium group (MA) and are used as both light absorbing material and hole conducting material (HTM) in this project. LÄS MER

  3. 22. Correlation of size and photoluminescence of single CdSe/ZnS quantum dots

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Fatjon Qejvanaj; [2012]
    Nyckelord :;

    Sammanfattning : In this thesis the correlation between size and emission wavelength of single CdSe/ZnS quantum dots (QDs) has been studied. Based on the quantum confinement model QDs of different size emit light of different wavelength. LÄS MER

  5. 24. Measuring the efficiency and charge carrier mobility of organic solar cells

    Master-uppsats, Institutionen för fysik

    Författare :ABASI ABUDULIMU; [2012]
    Nyckelord :Solar cells; P3HT; PCBM; shourt circuit current; open circuit voltage; maximum power; fill factor; efficiency; charge carrier mobility; CELIV; DI-SCLC;

    Sammanfattning : P3HT single layer, P3HT/PCBM bilayer and P3HT/PCBM inverted bilayer devices were produced by spin coating organic layers onto ITO patterned glass in air, and clamping it with an Au coated silicon wafer, as top electrode, at the end (Figure13). Normal and inverted bilayer devices were also fabricated with and without PEDOT:PSS. LÄS MER

  7. 25. Fabrication and Optical Properties of ZnO Nanocrystal/GaN Quantum Well Based Hybrid Structures

    Master-uppsats, Tunnfilmsfysik; Tekniska högskolan

    Författare :Kuo Chieh-Yi; [2012]
    Nyckelord :ZnO; GaN; Hybrid Structure;

    Sammanfattning : Optical properties of hybrid structures based on zinc oxide nanocrystals (NCs) and Gallium Nitride quantum well (QW) has been studied. The ZnO NCs thin films on the top of GaN QW structures were fabricated using spin coating. The surface morphology was characterized by scanning electron microscopy (SEM). LÄS MER
