本論文提出一款單軸追跡高效能環狀微結構平面式日光集中器,主要分成三個部分;第一部分利用百葉式太陽光角度調整器及稜鏡微結構板追跡太陽光使太陽光入射光角度減少;第二部分使用一種用來調製光線行進角度分布的裝置進行光線角度調製;第三部分為環狀微結構平面式日光集中器,第二部份調製光線結構利用全反射使入射光線依照旋轉矩形柱之結構行進至圓形之切線角度分布;第三部分集光結構利用全反射使經過第二部分結構之日光耦合至底端之導光板內以全反射行進,並在導光板中央以高效能光電轉換電池吸收並進行光電轉換。
本文所提出的太陽能集光系統實現了單軸追跡且在太陽光譜400 nm~900 nm的AM1.5光源模擬下,以系統位於台北之設定之下,可全年且每日8:00~16:00達到8小時全日追跡進行收光,且系統最高效率達到73.6%,平均效率亦達到70%,而集中比最高可達257,平均集中比則可達240。
The paper proposes a single-axis tracking high-efficiency ring-shaped micro-structure planar solar concentrator, which is mainly include three parts; first, uses a louver-type sunlight angle adjuster and prism plate to track sunlight to reduce the angle of incident light of sun; A device for modulating the traveling angle distribution of light rays and a ring-shaped micro-structure planar solar concentrator are used as the first and second segments of the light-concentrating structure. The first-stage modulated light structure uses total reflection to make the incident light travel according to the structure of a rotating rectangular column. The tangent angle distribution to the circle; the second section of the light-collecting structure uses total reflection to make the daylight passing through the first section of the structure be coupled to the bottom of the light guide plate for total reflection, and is absorbed and performed by the high-efficiency photoelectric conversion cell in the center of the light guide plate Photoelectric conversion.
The solar light collection system proposed in this paper achieves single-axis tracking and is simulated under the AM1.5 light source with a solar spectrum of 400 nm to 900 nm, and the system is under the setting of Taipei. During 7:00 to 17:00 reaches 8 hours of full-day tracking for light collection, and the maximum efficiency of the system reaches 73.6%, the average efficiency also reaches 70%, and the concentration ratio can reach up to 257, and the average concentration ratio can reach 240.
