摘要

III-V族集光型太陽能系統利用集光器收集更多光線來提升系統轉換效率。其中在設計高集光型太陽能系統時，系統的深寬比是非常重要的，擁有較高的深寬比可以提高機械抗震度，並且可降低高集光型太陽能系統的價格。在這項研究中，本文提出利用內全反射特性和圓錐部分，設計出新的III-V族集光型太陽能設計。
通過模擬數據發現，這種新的集光器可以提供更高的設計靈活性和更好的深寬比。在這項研究中，本論文中的主要集光倍率是1370X，深寬比為4.27，光學轉換效率為80％。此外，太陽能電池表面上的均勻性是0.375以及半接受角為0.586°。

A concentrator is used with an III-V multi-junction solar cell to form a high concentrated photovoltaic (HCPV) system, the conversion efficiency of the system can be increased due to more lights collected. In designing the HCPV system the aspect ratio is very important to practical usage and high value is desirable, an large aspect ratio will enhance machinery earthquake resistance so that the price of the whole HCPV system can be apparently reduced. In this study, the new design of solar concentrator composed of TIR section and conic section for III-V multi-junction solar cell is proposed.
Through simulation data, it is found that this new compound concentrator can offer a higher flexibility and a better aspect ratio. In this work, the main geometrical concentration ratio of this concentrator is 1370X, the aspect ratio of 4.27, and the conversion efficiency is 80%. Moreover, the uniformity of illumination on the surface of the solar chip is 0.375 and the half acceptance angle is 0.586°.
