摘　　要：在太阳能光热电转换利用的“三环节理论”模型的基础上,对太阳能光热电转换利用进行了经济学分析,并与常规火力发电的经济学作了对比,提出了化石能源的稀缺价值和环境成本的观点。探讨了聚焦型太阳能集热器的设计参数对太阳能光热电转换利用系统中单位输出价Cu 的影响。On the basis of Three Link Theory model concerning solar energy utilization for light,heat,and electricity conversion,the exergy economics analysis of solar energy utilization for light,heat,and electricity conversion has been carried out,and comparison with the exergy economics of conrvenetional thermal power-generation being made,and the concept of exergy price and enrironmental cost for unusual shortage of fossil energy being put forward.And the influence of design parameters for focussing type solar energy heat collector upon unit output exergy price Cu of the said solar energy utilizing system has been discussed.
