摘要:	聚光型太陽光電 / 太陽熱混合系統(concentrating photovoltaic and thermal systems, CPVT)是具潛力的潔能技術，用以將太陽能轉換為電與熱能。本研究提出一光束分頻CPVT架構，其藉由繞射光柵及平凸透鏡將太陽光之紅外波段與非紅外波段之光波分離，並分別導引至各自之接收元件。在繞射光柵方面，本研究設計閃耀式及二階式二型光柵，並分析光柵形狀誤差的影響。而在熱分析方面，藉由熱流原理分別針對此二型CPVT所使用之熱管進行溫度分布之模擬分析。再由模擬分析搭配實驗量測之結果推算閃耀光柵型與二元光柵型CPVT的總輸出效率分別為 43.37%, 40.22%。本研究之成果將作為未來實作光束分頻CPVT之參考。;A concentrating photovoltaic and thermal systems (CPVT) is a potential solar energy system for clean electricity and thermal generation. In this research, a spectral beam-splitting CPVT configuration is proposed based on the combination of a diffractive grating and a plan-convex lens to spectrally and spatially split infrared light and non-infrared light onto the receivers. Two types of gratings, blazed and binary phase gratings, are designed as the diffractive grating herein. Meanwhile, the shape distortion of the main component, the grating, is studied. Moreover, the temperature distribution of the heat pipe is simulated based on heat flux generated by a blazed grating or a binary phase grating. The total power efficiency of a CPVT show that the blazed and binary configurations has slightly higher from the estimated measurement are 43.37% and 40.22%, respectively. The research findings are expected to guide the designs of CPVTs based on diffraction optics and refractive lens.
