Abstract :
Detailed optical and electric models are presented to evaluate the performance of the two-stage dish concentrating spectral beam splitting photovoltaic/thermal (TDCS) system. It mainly consists of parabolic concentrator, spectral beam filter, heat receiver and the cell component. The beam filter coated with 38 layers is designed and manufactured. Three-dimensional optical model, considering the effect of solar intercept angle and tracking error, is developed using ray trace method. The spectral and spatial distribution of radiant intensity is investigated. The optical and splitting efficiency of the system at AM1.5 is 66.1% and 78%, alternatively. The total power generating efficiency of the system in theory is 18% with silicon solar cell with geometric concentration ratio 80. Beam splitting can reduce the solar cell temperature and increase concentration ratio together with photoelectric conversion efficiency.
