Abstract [en]

Energy harvesting - the conversion of ambient energy into electrical energy - is a frequently used term nowadays. Several conversion principles are available, e.g., photovoltaics, wind power and water power. Lesser-known are thermoelectric generators (TEG) although they were already studied actively during and after the world wars in the 20th century (Caltech Material Science, n. d.). In this work, the authors present a mathematical model for the calculation of input or output parameters of printed thermoelectric generators. The model is strongly related to existing models (Freunek et al., 2009; Rowe, 1995; Glatz et al., 2006) for conventionally produced TEGs as well as for printed TEGs. Thermal effects as investtigated by Freunek et al. (2009; 2010) could be included. In order to demonstrate the benefit of the model, two examples of calculations are presented. The parameters of the materials are derived from existing printing inks reported elsewhere (Chen et al., 2011; Wuesten and Potje-Kamloth, 2008; Zhang et al., 2010; Liu et al., 2011; Bubnova et al., 2011). The printing settings are chosen based on feasibility and convenience.

Abstract [en]

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. On the other, the high-­‐priced thermoelectric (TE) materials have an enormous impact on the costs per watt. In this thesis both factors will be examined: the production process and the selection of TE materials. Technical screen printing is a possible way of production, because this method is very versatile with respect to the usable materials, substrates as well as printing inks. The organic conductor PEDOT:PSS offers reasonable thermoelectric properties and can be processed very well in screen printing. It was demonstrated by prototypes of fully printed TEGs that so-­‐called vertical printed TEGs are feasible using standard graphic arts industry processes. In addition, the problems that occur with print production of TEGs are identified. Finally, approaches to solve these problems are discussed.
