所谓太阳能的研究和利用通常是指通过太阳能电池进行光电转换,或通过太阳能集热器进行光热转换。集热器虽然可以有各种各样的结构和形式,但都要有吸收太阳辐射能的吸收器。吸收器表面热辐射性能对集热器的热性能
The so-called research and utilization of solar energy usually refers to the photoelectric conversion by solar cells, or by solar collectors for photothermal conversion. Although the collector can have a variety of structures and forms, but have to absorb solar radiation absorber. Thermal performance of heat collector on absorber surface
