  1. 1. Screen Printed Thermoelectric Devices

    Författare :Andreas Willfahrt; Xavier Crispin; Werner Zapka; Linköpings universitet; []
    Nyckelord :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

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thermoelectric; Waste heat harvesting; Semiconductor; X-ray powder diffraction; SEM; Electron poor framework; EPFS; Green house effect; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : In today’s society, where energy conservation and green energy are buzz words, new scientific discoveries in green energy harvesting is key. This work focuses on materials capable of recycling low value thermal energy. LÄS MER

  7. 5. Growth and thermoelectric properties of CaMnO3-based thin films

    Författare :Erik Ekström; Per Eklund; Fredrik Eriksson; Biplab Paul; Erik Lewin; Linköpings universitet; []
    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
