    Sammanfattning : The increasing demand of renewable energy is the big driving force for the research and development of more efficient solar energy conversion solutions. Solar cells, which use the photovoltaic effect to convert the photon energy to electrical current, are an important solar energy conversion technique. LÄS MER

  5. 4. Nanoscale electrical properties of heterojunction interfaces for solar cells : modeling and experiments

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Martin Eriksson; [2018]
    Nyckelord :solar cell; heterojunction; ZnO; Cu2O; Comsol; atomic force microscopy; I-V characteristics;

    Sammanfattning :   A numerical model have been developed in order to describe and achieve deeper understanding of experimentally obtained I-V curves from Cu2O/ZnO p-n heterojunctions for potential use as future solar cell material. The model was created using the simulation software COMSOL Multiphysics® and their semiconductor module. LÄS MER

  7. 5. Processing Technology for Si Based Tandem Solar Cells

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

    Författare :Nedim Aydinci; [2014]
    Nyckelord :;

    Sammanfattning : This project focuses on the investigation of Silicon based Tandem solar cell fabricated by using the Hydride Vapor Phase Epitaxy (HVPE). In the state-of-the-art multi-junction solar cell manufacturing epitaxial technologies are used for sub-cell formation, such as MOVPE (Metal Organic Vapour Phase Epitaxy) [1] or MBE (Molecular Beam Epitaxy) [2].
