本計畫為一年之研究計畫，主要工作為研發雙反射鏡式聚光型太陽能電池 (Concentrated Photovoltaic，以下簡稱為CPV) 模組，包含集光器的光機設計與CPV 模組平板陣列之結構設計。本研究首先將依據雙反射鏡式集光器的光學設計，進行集光器光機初步設計與電腦實體模型建立，考量加工與組裝對位等功能性，設計反射鏡之形狀、結構與其固緊方式。然後建立集光器之光機有限元素分析模型，進行靜態結構分析，模擬反射鏡與挾持機構在不同追蹤角度與溫度變化之變形與應力。鏡片之變形結果可匯入光學軟體以分析其對聚光效果的影響，最後完成集光器之最佳化光機設計。此外，本研究也將針對CPV 模組平板陣列之支撐結構進行設計，並以有限元素結構分析輔助，探討模組平板陣列之樑框與支撐衍架結構在不同追日角度、風壓與溫度之變形，以得到輕量化、低變形與高熱穩定性之最佳化平板陣列結構設計。預期本研究之研究成果，將有助於提升國內雙反射鏡式CPV 模組之自主設計與分析之能力。 This project is a one-year project. The main goal of this project is to study the CPV (Concentrated Photovoltaic) module, including the optomechanical design of the concentrator and the supporting structure design of the CPV panel array system. Firstly, a preliminary optomechanical design of the concentrator and their solid model will be built based on the optical design of the double reflector concentrator. The shape, structure and mounting interface of the mirror will be designed, considering the manufacturing and alignment aspects. The finite element model of this concentrator will then be built, and static structure analysis will be performed to investigate the deformation and stress of the optical and mechanical elements under various tracking angles and temperature variations. Moreover, the mirror surface deformation determined from finite element analysis will be input into optical simulation software and the concentrating performance of the deformed mirrors will be studied. Based on the simulation results, an optimum design of the concentrator will achieved. Additionally, we will also investigate the supporting structure of the CPV panel array system. The deformation of the panel array frame and the truss frame under various tracking angles, wind pressure and temperature variations will be determined with the aid of finite element analysis. Finally, a panel array structure of lightweight, low deformation and high thermal stability will be finished. It is believed that the research results of this project will be helpful to improve the design, fabrication and assembly for reflective CPV modules. 研究期間：9901 ~ 9912
