  2. 1. Atomic layer deposition of zinc tin oxide buffer layers for Cu(In,Ga)Se2 solar cells

    Author : Johan Lindahl; Tobias Törndahl; Marika Edoff; Negar Naghavi; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CIGS; Solar cells; Thin film; Buffer layer; TCO; Window layer; Zinc tin oxide; ZTO; Indium oxide; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : The aim of this thesis is to provide an in-depth investigation of zinc tin oxide, Zn1-xSnxOy or ZTO, grown by atomic layer deposition (ALD) as a buffer layer in Cu(In,Ga)Se2 (CIGS) solar cells. The thesis analyzes how changes in the ALD process influence the material properties of ZTO, and how these in turn affect the performance of CIGS solar cells. READ MORE

  4. 2. Osteogenesis Imperfecta : Genetic and Therapeutic Studies

    Author : Katarina Lindahl; Östen Ljunggren; Andreas Kindmark; Carl-Johan Rubin; David Sillence; Uppsala universitet; []

    Abstract : Osteogenesis imperfecta (OI) is a heterogeneous disease of connective tissue, the cardinal symptom being fractures and severity ranging from mild to lethal. Dominant mutations in collagen I, encoded by COL1A1 and COL1A2, cause >90% of cases. READ MORE

  5. 3. Human Dermal Fibroblasts in Tissue Engineering

    Author : Johan Junker; Gunnar Kratz; Hans Johnson; Anders Lindahl; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The loss or failure of tissues and/or organs is one of the most frequent problems in modern healthcare. The field of tissue engineering applies the principles of biology and engineering in order to develop functional substitutes for damaged tissues. READ MORE

  6. 4. Ramification numbers and periodic points in arithmetic dynamical systems

    Author : Jonas Nordqvist; Karl-Olof Lindahl; Johan Öinert; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ramification numbers; local fields; arithmetic dynamics; periodic points; Nottingham group; Mathematics; Matematik;

    Abstract : The field of discrete dynamical systems is a rich and active field of research within mathematics, with applications ranging from biology to computer science, finance, engineering and various others. In this thesis properties of certain discrete dynamical systems are studied together with number theoretic properties of the functions defining these systems. READ MORE

  7. 5. Human Behaviour in Social-Ecological Systems : Insights from economic experiments and agent-based modelling

    Author : Caroline Schill; Therese Lindahl; Anne-Sophie Crépin; Johan Colding; Carl Folke; Juan Camilo Cárdenas; Stockholms universitet; []
