  1. 1. Effects of the interfaces in planar hybrid lead trihalide perovskite solar cells with n-type and p-type inorganic charge transport layers

    University essay from KTH/Energiteknik

    Author : Olivier Jaques Henri Fournier; [2018]
    Keywords : ;

    Abstract : Perovskite-solceller är en framväxande och lovande tunnfilmsteknik, som uppnådde hög effektivitet på en ofantlig kort tid. Den nuvarande arkitekturen i cellen, som innefattar titanoxid och Spiro-OMeTAD (en organisk förening) som laddningstransportlager (CTL), saknar stabilitet och visar hysteretiskt beteende. READ MORE

  3. 2. Light emitting diodes based on n-type ZnO nanorods and p-type organic semiconductors

    University essay from Institutionen för teknik och naturvetenskap

    Author : Raja Sellappan; [2008]
    Keywords : ZnO; ACG; organic; Inorganic; Polymer; nanorods;

    Abstract : The aim of this thesis work was to fabricate a hybrid LED using organic-inorganic ZnO materials. The goal of the project was to get an efficient white light emission from zinc oxide (ZnO) nanorods active layer. READ MORE

  5. 4. Investigation of Structural and Optical Properties of Nanocrystalline ZnO

    University essay from Institutionen för fysik, kemi och biologi

    Author : Sajjad Hussain; [2008]
    Keywords : Investigation; Structural; Optical; Properties; Nanocrystalline; ZnO;

    Abstract : The structural quality of material (concentration and nature of defects) and optical properties (intensity and spectral emission range) of semiconductor materials are usually closely correlated. The idea of this work was to carry out a basic characterization of the structural (by X-ray diffraction technique and scanning electron microscopy) and optical (by micro photoluminescence measurements) properties of nanocrystalline ZnO samples and find a correlation.
