本研究利用精密塗佈設備於玻璃上噴塗抗反射溶液，達到減少太陽光的反射提升光穿透率的效果，在太陽能板噴塗抗反射層，能提高太陽能電池模組的光電轉換效率，使其太陽能模組系統輸出功率最大化；塗佈抗反射層同時能降低玻璃的眩光反射，減少反射光對環境的污染。採利用超音波噴塗方式，將奈米溶液塗佈於玻璃表面以作為玻璃的抗反射層，藉由此噴塗方式可大面積製造，且比一般氣壓式噴塗可節省材料用量，膜厚均勻性可控制在10%以內，經實驗將超音波塗佈設備其關鍵參數設定如下，XY軸移動速度：150 mm/s、噴塗液流動速度：1 cc/min、導流強度：29 psi，在此條件下玻璃之光穿透率可提高約2.5%，證實本研究對於玻璃抗反射應用之可行性。研究標的為986 mm × 1700 mm大面積噴塗、降低噴塗設備建置成本及提升薄膜光穿透率，經實驗驗證由參數的調整，可將噴頭數量由原本64組噴塗頭，降低至9組噴塗頭。若考慮光穿透率及薄膜均勻性均達到較佳性能，噴頭數量43支時可提高光穿透率2.03%；若考慮光穿透率較佳而忽略薄膜均勻性，噴頭數量20支時可提高光穿透率2.05%；若降低光穿透率及薄膜均勻性，只考慮噴頭數量，噴頭數量9支時可提高光穿透率1.89%。在以提高光穿透率為1.89%的條件下，透過噴塗頭最佳化配置分析，實際驗證當改變超音波噴塗設備噴塗參數，可減少噴塗機噴頭數量、可快速大面積塗佈及降低模組建置成本達85.9%。

This study used precision coating equipment to spray antireflection solution on glass reducing the light reflection and increasing light transmission. The output power of a solar panel coated with an antireflection layer can be enhanced, and the system output power can be maximized. The glare reflected by glass can be reduced and also minimarize the pollution of reflected light to the environment. This study used ultrasonic spray coating to coat a glass surface with a nano-solution as the antireflection layer. This spray coating mode is applicable to large area spray coating, which can reduce material consumption, as compared with general vapor-pressure spray coatings. Film thickness uniformity can be controlled within 10%. The key parameters of ultrasonic coating equipment were set as follows: X and Y axes movement speed at 150 mm/s, spray coating liquid flow rate at 1 cc/min, and diversion intensity at 29 psi. The glass transmission can be increased by 2.5%, which proves the feasibility of the application to glass antireflection. This research is focused on reducing the implementation costs and enhancing the optical transmittance of the thin film over an area of 986 mm x 1700 mm. A key cost factor is the number of spray nozzles used in the equipment. The number of spray nozzles in the original spray head can be reduced from 64 to 9 nozzles. Taking optical transmittance and film uniformity into consideration, increasing the number of nozzles to 43 can increase optical transmission by 2.03%. If coating uniformity is ignored, the number of nozzles can be decreased to 20 to give a 2.05% increase in optical transmission. If neither optical transmission nor coating uniformity are considered, reducing the nozzle number to 9 can improve optical transmission by 1.89%. Optimization configuration analysis was then conducted on the system to maintain this 1.89% optical transmission improvement. Experiments confirm that variations in spray parameters can reduce the number of nozzles needed, whilst achieving rapid coating over large areas and reducing the cost of module construction by 85.9%.
