Objectives

  • Measurement of the density-of-states (DOS) of doped organic semiconductors and linking the DOS to the Seebeck coefficient and conductivity
  • Development and validation of multiphysics models for device design
  • Optimization of device design through the use of multiphysics modelling

Expected results

  • Measurement of the DOS in a number of n- and p-doped systems as well as on hybrid systems
  • The establishment of a direct link between DOS and Seebeck coefficient in doped organics semiconductors
  • Development and experimental validation of multiphysics models for organic thermoelectric devices
  • Improved and optimized design of organic thermoelectric generators

Skills acquired

  • Finite-element modelling of thermoelectric devices
  • Electrical characterization and electrochemical measurements of the DOS
