摘　　要：本文针对目前分频型光伏光热接收器效率普遍不高的问题,基于体积吸收式复合分频的优势,设计了一种新型体积吸收式复合分频聚光光伏光热接收器。采用LightTools软件对太阳辐射由聚光器到接收器内部传播全过程进行完整模拟。结果表明,接收器中光热接收器可吸收61.17%的光,光伏组件可接收33.67%的光,其中光伏组件接收到的光中,电池高响应的650~1100 nm波段占比可达92.38%;光伏电池对经分频后的光的光电转化效率可达27.02%,比未分频情况下提升了10.42%。所设计的复合分频接收器电、热效率分别为9.1%和40.78%,相对未分频光伏系统其综合性能可提升31%以上。In order to solve the problem of the spectral splitting photovoltaic/thermal(PV/T)solar receiver with low efficiency,a new spectral splitting PV/T volumetric solar receiver is designed in this paper,which is based on the advantage of the combined volumetric absorber.A complete solar radiation propagation process from concentrator to receiver has been simulated by LightTools.The results indicate that the thermal receiver can absorb 61.17% of the light,and 33.6% of the light received by PV module.92.38% of the light received by PV module is between 650 nm and 1100 nm,within which the cell has a high response.The PV conversion efficiency of cells can reach 27.02% by filtering,with 10.42% improvement compared to unfiltered cell.The theoretical electrical and thermal efficiency of the receiver are 9.1%and 40.78% respectively.Using the combined filter for silicon CPV cell produces more than 31%comprehensive performance when compared to PV alone.
