| Summary: | 碩士 === 臺灣大學 === 光電工程學研究所 === 98 === In the first chapter of this thesis will introduce the basis of semiconductors, including the PN junction, principle of solar cells and efficiency calculations. When the high efficiency of solar cells sprout slowly, after the cost of high efficiency would require higher costs, and in order to bring a large area of light energy can be collected on a smaller area of the solar cell, which is our focus - Solar Concentrator, it will then introducing the various forms of solar concentrator and applications.
In the second chapter will introduce the basis principles of optics and electromagnetic theory, such as the Huygens principle and the derivation of Snell’s Rule. And then further derive the TE wave and TM wave reflectivity formula, and finally will be introduced how to design the AR coating film.
In the third chapter will introduce the main theme of this thesis, using circular prisms array to construct a solar concentrator, as we will make use of FRED optical-tracing software to simulate the efficiency of this concentrator and its receiving angle relationship. The geometric concentration ratio of the disk-like module alone is 93 with a high efficiency of 90%, and the overall geometric concentration ratio of a combination of a Fresnel lens with NA value of 0.086 and our device can be as high as 837 with an efficiency of 92%.
