  1. 1. Screen Printed Thermoelectric Devices

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Andreas Willfahrt; Linköpings universitet.; Linköpings universitet.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Screen printing; thermoelectric generator; Seebeck effect; energy harvesting;

    Sammanfattning : Thermoelectric generators (TEG) directly convert heat energy into electrical energy. The impediments as to why this technology has not yet found extensive application are the low conversion efficiency and high costs per watt. On the one hand, the manufacturing process is a cost factor. LÄS MER

  4. 4. Growth and thermoelectric properties of CaMnO3-based thin films

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Erik Ekström; Linköpings universitet.; Linköpings universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The field of them1oelectrics started in early 19th century. Since the discovery of the Seebeck effect and the Peltier effect, thermoelectric modules have found their way into, mostly, niche applications such as radioisotope thermoelectric generators on space missions. LÄS MER

  5. 5. Design of Transition-Metal Nitride Thin Films for Thermoelectrics

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Sit Kerdsongpanya; Linköpings universitet.; Linköpings universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Thermoelectric devices are one of the promising energy harvesting technologies, because of their ability to convert heat (temperature gradient) to electricity by the Seebeck effect. Furthermore, thermoelectric devices can be used for cooling or heating by the inverse effect (Peltier effect). LÄS MER
