中文摘要：

结合STP（Solar thermal Propulsion）高温吸热芯的技术特点,采用二次分光膜,对STP热辐射光伏发电（TPV）系统进行了结构设计和性能计算。通过优化分析,得到使太阳电池工作温度在额定值附近的氢冷却剂入口参数和通道尺寸数据。计算结果表明,当吸热芯温度为2400K时,光伏电池组件的输出功率在50～100W之间;通过调节电池组件的串并联电池数量,可以获得期望的输出特性。结论为STP的热光伏发电系统的设计研究提供参考依据。

英文摘要：

Based on high temperature characteristics of solar absorber of solar thermal propulsion（STP）,a thermal photoelectric（TPV） system is designed and simulated in this paper.The inlet parameters and channel sizes of hydrogen coolant which make the working temperature of PV module approach the rated value are obtained by investigating the temperature field of PV module.The calculational results show that the output of PV module is about 50 to 100W at the absorber temperature equal to 2400K.The expected I-V characteristics would be realized by regulating the number of series/parallel cells.The conclusions are valuable for investigations of thermal/PV system of STP.
