摘要

本論文主要製備出新穎的p-n異質接合太陽能電池,使用BOE清洗Si基板的表面SiO2之後使用低成本，低溫水浴法製備ZnS薄膜薄膜作為異質接面太陽能電池的n型接面，在使用RF sputter 鍍上AZO最後在鍍上Al電極製作成元件，由於ZnS薄膜厚度與溫度是重要的部分。薄膜需要良好穿透率，均勻性透過UV光分析ZnS的透光度，內容主要分為兩個部分：第一部分合成ZnS粉末的奈米球結構末之薄膜光學特性和表面形貌之後製備新穎的AZO/ZnS/p-Si異質結構太陽能電池；第二部分利用等向性濕蝕刻，製作金字塔結構降低反射率。最後使用太陽光模擬器量測效率

This thesis focuses on the fabrication of a pn heterojunction solar cell. Using a low-cost BOE solution, the Si substrate was cleaned of SiO2, and a low-temperature bath was used to prepare the n-ZnS section of the heterojunction solar cell. The AZO layer was then added using RF sputtering, and the Al electrode was lastly plated on to complete the solar cell. Analysis of the solar cell’s performance in uniform UV light shows that the solar cell has two main elements. First is the ZnS film, synthesized using the method. This method results in the ZnS having luminescent and optical properties due to its nanosphere structure and surface morphology of the film. It is that the solar cell is a novel AZO/ZnS/p-Si heterojunction solar cell. Second is the isotropic wet etching used to fabricate pyramid textures to minimize reflection. The effect of the ZnS layer’s thickness and temperature on the solar cell’s efficiency was also investigated using a solar simulator to measure the efficiency.
