bstract Finite Element Method (FEM) is an effective and productive tool which is able to deal with sophisticated engineering requirements and successfully calculates expected output values often based on advanced boundary conditions and solution settings. The paper refers to modelling of thermoelectric generators in FEM environment (ANSYS software) which are based on popular Peltier modules that are frequently used in energy cogeneration branch of industry. The modelling process consists of geometry design, sensitivity study which focus on solver settings, discretization level and their impact into results (optimization of solution process total time). Last step engages parameter of Seebeck coefficient. Its modification allows adjusting the FE analysis to experimental data. The verified thermoelectric module will be able to reflect real capabilities of the commercially available thermoelectric devices. The main purpose of the process development is creation of Peltier modules (accessible in industry) FE models database. The devices from the database could easily be used in sophisticated FE analysis which consists of various physics systems (coupled) where simplified approach or indirect method will be limited or impossible to use.

1 Introduction Poland as a member of European Union is obligated to meet requirements related to climate protection (40 % reduction of CO2 emission, in comparison to year 1990) and development of Renewable Energy Sources systems (contribution up to 27 %,) and their efficiency (27 %) in the energy industry up to 2030 year. According to the mentioned data, the reduction of greenhouse gas emissions (40 % in comparison to year 1990) and the natural environment protection is very important aspect of modern technology progression in the near future. Industrial companies from various market sectors (automotive, military, electronic, etc.) direct their attention to distributed generation of energy sources [1–4]. Nowadays, so-called energy cogeneration becomes more and more popular not only in the industry market but also among private individuals. One of the common group of innovative technologies is Renewable Electricity Production. Examples of mentioned subject are systems which are based on solar energy, wave movements, piezoelectric devices, Peltier modules, etc. The last from specified subgroup is able to work as a thermoelectric generator (TEG). The main effect which allows electricity production in this case is Seebeck phenomenon (common usage of the modules
