| Abstract: | Solar thermal power generation technology is a high-grade solar energy utilization technology by which the solar energy is first transformed into thermal energy and then the thermal energy is partially used to drive a generator to produce electric power via a thermodynamic cycle. In the present paper, the overall layout in the research field of solar thermal power generation technology in China is summarized. The ener-gy conversion processes from solar energy into electrical energy via thermal energy and the related basic sci-entific issues are analyzed. It is pointed out that the basic research needs in the solar thermal power genera-tion technology are the heat transfer mechanism and heat flux characteristics in the energy transfer and con-version processes, the integration theory in the conversion of system of light-heat-eletricity, and key mate-rials and technology. At last, the priority in funding areas in the field of solar thermal power generation of the National Natural Science Foundation of China is presented. |
