摘要


本論文設計的環狀微結構平面式太陽能集光器,利用具有拋物線截面輪廓的環狀微結構作為集光結構,能夠利用內部全反射將入射太陽光匯聚並且耦合到下方的導光板,再由下方導光板將光線導引到導光板中心處匯集,得到更高的照度集中度,本論文提出兩種架構,一種模型是效率可達八成以上,但容忍角達正負兩度,一種是能讓容忍角到達12度,效率四成以上,再搭配上本論文百葉設計,能夠讓容忍角提升到60度。

This study is to design a Planar solar concentrator with circular microstructures. We utilized a parabolic structure, which can concentrate the incident onto a light guide plate(LGP) by total internal reflection (TIR), get a higher of illumination concentration. There are two architectures, one is keep 80% but tolerance ± 2 °, another is keep 40% but tolerance + 12°, with blinds design can achieve + 60°.
