本論文設計了一新型的平板式太陽能集光器,使用了獨特的耦合結構,不同於常見的透鏡陣列及稜鏡耦合結構組合,利用拋物結構作為基底的耦合結構,其同時具備了縮小光點及耦合光線特性,有效的使兩個結構合而為一,且利用全反射方式使入射光耦合入板,不受波長影響;搭配上本論文提出的單軸機械追跡及可替換的稜鏡膜片所組成的追跡系統,最高可達到500x集中度,71.3%的光效率,而在偏差±0.5°之內,仍能維持63%以上的效率。
This study is to design a new type of planar solar concentrator, using a unique coupling structure, different from the common structures composed of lens array and coupling prism. We utilized a parabolic structure, which can concentrate the incident light onto a narrow spot by total internal reflection (TIR), to couple the light in to a light guide plate with free of color dispersion. With a tracker composed of a single-axis tracker and replaceable prism sheets, simulation results show that the proposed planar solar concentrator can achieve a maximal optical efficiency 71.3% at 500×concentration, and keep a efficiency63%withthe deviation of tracking angles by ± 0.5 °.
