3. 2. 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
