Performance study on a dye-sensitized solar cell and thermoelectric hybrid power system

A theoretical model of the dye-sensitized solar cell-thermoelectric hybrid power system is established, which is composed of the dye-sensitized solar cell module and thermoelectric generator module. Based on the theory of non-equilibrium thermodynamics, the expressions for the power output and efficiency of the hybrid power generator system are derived. The general performance characteristics of the hybrid system are analyzed. The optimally operating conditions of the hybrid system at the maximum output power and efficiency are determined. The influence of some main performance parameters on the performance characteristics of the hybrid system are discussed in detail. The results show that the low grade waste heat of the dye-sensitized solar cell module can be effectively used by the thermoelectric generator and the power output and efficiency of the hybrid system can be improved The results obtained in this paper may provide theoretical significances for the design and optimal operation of practical dye-sensitized solar cell-thermoelectric hybrid power generator system.
