Abstract:

Concentrated solar power generation technology is one of the most important approach of the solar thermal utilization due to its stability, controllability and high capacity. The photon-thermal conversion efficiency of the solar concentrator is the main factor that influence the power generation capacity and the photon-electric conversion efficiency of the concentrated solar thermal power station. In this paper, the recent key technologies of improving the optical-thermal conversion performance of the solar concentrators were summarized via three aspects, including optical structures, receiver structures and heat transfer fluid. The advanced optimization strategy and the performance improvements of the concentrators, as well as the limitation, were presented. On the basis referred, the perspective of the solar concentrator technologies was analyzed.
