摘要
文中提出一种基于GaAs电池与纳米流体分频的全光谱发电系统,这一系统利用基于纳米流体的光谱分频技术将光伏与光热两种常见的发电系统整合为一,能够充分利用全谱段的太阳能.通过对系统进行数学建模,研究了关键参数对系统发电效率的影响,分析了该发电系统相较于单一光伏发电或光热发电所具有的优势.结果表明,全光谱发电系统相较于单一光伏或光热发电系统优势明显.当系统性能参数取得最优时,全光谱发电系统相比同条件下的单一光伏发电系统发电效率最高可提升4.8%,相比同条件下的单一光热发电系统发电效率最高可提升1.9%,其中回收电池废热的措施可使系统的发电效率提升2.3%.
A full spectrum power generation system based on GaAs cell and nanofluid spectral splitting is proposed in this paper.This system integrates photovoltaic and photothermal power generation systems into one by using the nanofluid spectral splitting technology,which can make full use of the solar energy in the full spectrum.Through the mathematical modeling of the system,the influence of key parameters on the power generation efficiency of the system is studied,so as to further study the advantages of the power generation system over single photovoltaic power generation or photovoltaic power generation.The results show that the full spectrum power generation system has obvious advantages over the single photovoltaic or photothermal power generation system.When the performance parameters of the system are optimized,the generation efficiency of the full spectrum power generation system can be up to 4.8%compared with the single photovoltaic power generation system under the same condition,and 1.9%higher than that of the single photovoltaic power generation system under the same condition.Among them,utilization of waste heat from the battery can increase the generation efficiency of the system by 2.3%.
