碩士 === 元智大學 === 光電工程研究所 === 99 === This study is about the important field of energy development-solar cell. Solar cell is varied, among them the multi-junction tandem solar cell is the most efficient. This thesis investigates the research and fabrication of triple-junction tandem Ⅲ-Ⅴ compounds solar cells. The main topic is substitute of current single or multi-junction anti-reflection layer, and reduces the cost of fabrication. The surface of device adopts novel nano-imprint approach for Sub-wavelength Structure. And we simulate the best depth of etching with APSYS, software for optical properties. There are two patterns for structure of silicon nitride, Rod and Hole. We use this method for the anisotropic etching surface nanostructure of Ⅲ-Ⅴ compound solar cells, and transfer the pattern to the structure below. This technique is suitable for solar spectrum than single or multi-junction anti-reflection layer. It is expected for application of high efficiency solar cell in the future.
