  1. 1. Loss Mechanisms In Non-Fullerene Organic Solar Cells

    Författare :Huotian Zhang; Feng Gao; Olle Inganäs; Weimin Chen; Jenny Nelson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photovoltaics; organic solar cell; non-fullerene; charge recombination; voltage loss; fill factor;

    Sammanfattning : Photovoltaics are one of the most important sustainable energy sources in the 21st century. Among photovoltaics, organic solar cells (OSCs) offer many advantages such as ease of processing, lightweight, the potential for flexibility, and tunable properties. Its peculiar nature and complexity present a fascinating charm, attracting many researchers. LÄS MER

    Sammanfattning : Nowadays, cameras are everywhere thanks to the tremendous progress on sensor technology. However, their performance is far away from what we experience by our eyes. LÄS MER

  4. 3. Fill factor of organic solar cells and applications of dilute donor devices

    Författare :Nannan Yao; Fengling Zhang; Jonas Bergqvist; Jan van Stam; Weimin Chen; Julia W. P. Hsu; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Organic solar cells (OSCs) have attracted great attention due to their low cost, flexibility and solution-processibility. In recent years, the development of nonfullerene acceptors (NFAs) has truly promoted the efficiency of OSCs up to 19%, implying high potential for commercial applications. LÄS MER

  5. 4. Understanding information sharing in supply chains - Identifying contingency factors that impact benefits of information sharing

    Författare :Joakim Kembro; Teknisk logistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Logistics; Supply chain; Supply chain management; Information sharing; Information flow; Demand data; Contingency theory; Contextual factor;

    Sammanfattning : To increase our understanding of information sharing in supply chains the purposeof this licentiate was threefold: to review and analyze existing academic literature to describe and structure the research field; to empirically explore information sharing in a supply chain representing more than three tiers; and to explore contingency factors through literature reviews and empirical data collection. Thereby this licentiate thesis addresses several gaps identified in academic literature. LÄS MER

  7. 5. Role of corticotropin-releasing factor, somatostatin and leptin in vagal nerve function and control of gastric emptying

    Författare :Ulrika Smedh; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The overall aim of this thesis was to study the effects of centrally acting CRF and leptin, and peripherally acting somatostatin on gastric emptying of glucose. Freely moving rats bearing chronic intragastric fistulas received intragastric infusions (1.0 ml/min) of glucose (12.5 % or 25 %) during 6-18 min. LÄS MER
