摘要

目前太陽能電池發展趨勢因為成本與效率的因素，主要是以研發薄膜型太陽能電池為主軸，但薄膜型太陽能電池的光電反應層較一般太陽能電池薄，光線在光電反應層的路徑相對地減少很多，效率亦會降低，因此許多研究單位均以提升光在光電反與層的路徑為目標。
本論文主要是研究太陽能電池不銹鋼基板織質結構的成形，利用黃光微影製程與蝕刻技術將不規則、特殊圖形，如不同尺寸、不同間距、不同幾何形狀等織質結構成形在不銹鋼基板上；另一部分，利用電解拋光(EP)、鍍銀等表面處理來提升不銹鋼基材的光譜的全反射率及漫反射率。最後進行不銹鋼表面織質結構的光譜檢測及與鍍膜的附著力測試，了解不同織質結構與光譜特性、附著力的關聯性。
在光譜研究中，不同織質結構會有不同的光譜規則性，但某些織質結構因蝕刻製程不易控制而無法判讀其規則性；在附著力研究中，因鍍膜製程是利用蒸鍍方式，附著力太差而無法讀取其附著力數據，因此應改用其它的鍍膜製程或是改用ASTM中的膠帶測試法量其附著力。

Due to cost and efficient considerations, current research development of solar cell mainly concentrates on thin film solar cell. However, photoelectric layer of thin film solar cell is thinner than solar cell and beam route of reactive layer will be abbreviated and the reaction efficient will be decreased. As a result, most research organizations stress on improving beam route.
The aim of the research focuses on the texture forming process of stainless steel substrate of solar cell. Via photolithography Process and etching techniques, irregular and special figures in different size, distance and texture forming conditions are formed on stainless steel substrate. Based on surface processing of electropolishing(EP) and silver-planted process, total reflection and diffuse reflection of spectrum can be advanced. Lastly, in order to understand the correlation among various texture structure, characteristic of spectrum and adhesion capability, spectrum examination on stainless steel surface and adhesion capability of sliver-plated process will be tested.
Under spectrum research, various texture structures will result in different spectrum regulations. Nevertheless, due to controlling difficulties in etching process, the regulations of some texture structures can not be clarified. In adhesion experiment, because of the choice of evaporation method in silver-plated process, adhesion capability is too poor to assess. Hence, other plated process and tape test of ASTM are recommended to use in adhesion test.
