【Abstract】

The experimental I-V characteristics of a Si cell module in a thermophotovoltaic system using a SiC radiator were investigated.The results demonstrate that the short-circuit current increases while the open-circuit voltage,especially the fill factor decreases as cell temperature increases when the radiator temperature increases from 1273K to 1573K,leading to a lowered increase of the system output power.The maximum output power density of the cell module is 0.05W/cm 2 .The values of the open-circuit voltage and the maximum output power obtained by theoretical analysis agree well with the experimental ones.But the theoretical short-circuit current are higher because of the existence of contact resistance inside the cell module.In addition,the performance and cost of a TPV cogeneration system using industrial high-temperature waste heat were analyzed.The system electrical efficiency is 8.6% when the ytterbium oxide radiator temperature is 1573K.The system cost and investment recovery period are 13105EUR/kW el and 10 years,respectively.
