本研究應用二次光學元件設計方法,利用等光路設計建構太陽能聚光器,使用光學模擬軟體分析其光學效率、容忍角度與輻射照度等。主要目的為提升太陽能聚光器的容忍角度,降低太陽偏差角度所造成的能量損失,以及使能量分佈均勻,提升發電效益。本研究比較四種不同的二次光學元件:折射式等光路設計之二次光學元件、折射式金字塔型二次光學元件以及反射式金字塔型二次光學元件、實現同步多曲面設計方法設計之複合式太陽能聚光器,模擬初始設計並進一步進階設計,分析其光學特性並進行比較。論文中針對容忍角度較佳的折射式等光路設計之二次光學元件探討在多波段與組裝誤差的情況下,對於聚光器之光學特性造成的影響。Based on the design methods for secondary optical elements, this thesis utilizes the equal optical path to build the solar concentrator and the optical simulation software to analyze the optical efficiency, acceptance angle and irradiance. The primary purpose is to improve the acceptance angle of solar concentrator, reduce the energy loss caused by sun angle deviations, distribute the energy evenly and finally promote the benefit of power generation.In this paper, four types of secondary optical elements are compared, including kaleidoscope with equal optical path design, kaleidoscope with flat top surface, specular pyramid and the compound solar concentrator via the simultaneous multiple surfaces design method. This study simulates the initial design and carries out the advanced design, so as to analyze and compare the optical properties.This thesis also analyzes the impacts of the broad band and assembly errors on the optical performance of the type of kaleidoscope with equal optical path design.
