人類為了解決全球暖化問題，積極建置再生能源以取代石化燃料，進而。然而，比起傳統能源的成本，再生能源目前尚未具有競爭力。在產品品質與生產效率必須再精進，以降低製造成本。而在太陽能電池製造中，轉換效率是價格競爭力中最重要的決定因子，也是製造商首要改善的項目。
為符合以上需求，本研究提出運用工業4.1技術建構先進製造物聯雲。首先，全自動虛擬量測系統提供了全面品檢功能，藉由每一批品質狀況透明化，進而達到即時監控，以達到「零缺陷」境界；第二，發展管對管控制，並結合信心指標與相似度指標，避免不可靠的預測結果被運用在配方的自動調適，改善製程能力；最後，發展全廠智慧型預測保養系統，並設計可管理化的機台健康指標架構，提升機台的可用率。本研究以太陽能電池製造中的關鍵製程，抗反射層為實作範例說明。

A massive uptake of renewable energy can hopefully replace fossil fuels and solve global warming problem. However, the cost of renewable energy is not comparable with traditional energy. The product quality and production efficiency need to be optimized in order to reduce the manufacturing cost. In solar cell manufacturing, the transformation efficiency of solar cell is a critical factor for price competition, and it is also the top priority of cost improvement.
To fulfill the requirements stated above, the author proposes an advanced manufacturing cloud of things (AMCoT) by utilizing industry 4.1 technologies. The automatic virtual metrology (AVM) system provides total inspection to achieve the goal of zero defects production; then tube-to-tube (T2T) control with reliance index (RI) and global similarity index (GSI) help to improve the process capability; finally, factory-wide intelligent predictive maintenance (IPM) system increases the tool availability. Anti-Reflection Coating (ARC), the most critical process of solar cell manufacturing, will be used as illustrative example.
