Thermophotovoltaic (TPV) energy conversion systems convert solar energy into electricity via thermally radiated photons at tailored wavelengths to increase energy conversion efficiency. In this study, we report the design and analysis of a TPV system with one-dimensional photonic crystals (1DPCs) filter using thermal electrical model that includes the thermal coupling between the emitter/filter (PhCs)/PV cell. The performance of the proposed structure, one-dimensional photonic crystals (TiO2/SiO2) 6 with P periods of Titanium Dioxide (TiO2)and Silicon Dioxide (SiO2) of thermophotovoltaic system, has been studied by Mbakop et al [1] and Banerjee et al[2]. The temperature distribution and electrical power output of TPV cell are calculated at a heat varying from 1000 K to 1600 K using parametric solver at a regular interval of 25 K. Furthermore, voltaic efficiency distribution in a concentrating thermal photovoltaic system is presented.
