近年來太陽光電產業技術已相當純熟，從矽晶圓到太陽電池模組，並實際運用於戶外的太陽能發電廠與各種商品。太陽光電產業製程包含太陽電池製作、模組化之焊接與層壓製程，以及太陽能發電廠之系統架構，皆需精進其相關技術，然而於商品運用上重要之關鍵技術則為模組製作過程，其涵蓋太陽電池切割、焊接製程、層壓製程與太陽電池模組品質檢測，為此本研究將探討太陽電池於層壓製程之參數最佳化。
　　本研究採用二階反應曲面法針對太陽電池模組之填充材料乙烯-醋酸乙烯共聚物(Ethylene Vinyl Acetate, EVA)於層壓製程中，各項參數對EVA膠合與光學特性進行探討分析，以及將參數優化之結果實際運用於多晶矽太陽電池模組封裝上。填充材料EVA之品質特性，包含表層材料剝離強度、背板材料剝離強度與光線穿透率，而影響品質特性的品質因子有底板溫度、抽真空時間、交聯時間、保壓壓力與EVA種類，各因子採業界之水準條件由低水準至高水準取三個水準值，以中央合成設計(Central Composite Design, CCD)進行實驗設計規劃，就各疊層材料與EVA之剝離強度及光線穿透率做實驗量測以確認品質特性差異，並經由變異數分析其品質特性後，可獲得顯著影響之因子，且建立數學模型與回歸方程式。
　　研究發現表層材料之剝離強度及光線穿透率影響因子為底板溫度與抽真空時間，背板材料之剝離強度影響因子為底板溫度與交聯時間，經由參數優化後最佳之表層材料剝離強度為9.544 N/cm，背板材料剝離強度為116.193 N/cm，光線穿透率為68.686 %(200~1100 nm全光譜範圍平均值)，而為驗證分析預測值，本研究將優化結果之參數再次實驗，確認其可靠性，實驗結果差異值低於10 %。最後將參數優化之製程參數使用多晶矽太陽電池實際封裝成模組並量測其發電功率，研究結果顯示經層壓製程後太陽電池裸片功率由原功率3.877 W提升至4.013 W，其增益值達到3.51 %，故利用反應曲面法優化層壓製程確實能有效且快速地獲得最佳製程參數與品質特性。

　　Photovoltaic(PV) industry like silicon wafer or PV module has been well developed recently and applied to many outdoor products and power plants. The fabrication of PV industry includes the solar cell production, soldering process, laminating process and system structure of solar power plant. To increase the efficiency and reliability of PV modules, the focus of this research is mainly on the optimal parameters on encapulation process of PV module.
　　In this study, the second-order Response Surface Method(RSM) is used to analysis the quality factors of Ethylene Vinyl Acetate(EVA), i.e., filler material, during the encapulation process. Through systematic experimenting and regression analysis, the relationship between quality characteristics and quality factors is found in order to establish approximate responses. Looking at the encapulation process on the lamination machine, these quality factors(variables) are, heating conditions, vacuum time, cure time, hold pressure and the kind of EVA used. We set the level in each factor to reflect data from industries. The levels were chosen three standard values from low to high. In addition, the peel strength of the frontsheet/EVA, the peel strength of the EVA/backsheet and the transmittance of EVA are set up as quality characteristics (response). Then, through systematic experimenting and regression analysis, the relationship between response and variable is found in order to establish approximate responses by the Central Composite Design(CCD).
　　The results are shown that the impact factors of the peel strength of the frontsheet/EVA and the transmittance of EVA are heating conditions and vacuum time; while the impact factors of the peel strength of the EVA/backsheet are heating conditions and cure time. Through the optimization of RSM, the peel strength of the frontsheet/EVA is up to 9.544 N/cm and the peel strength of EVA/backsheet is up to 116.193 N/cm. The transmittance of EVA is 68.686 % under average range of the spectral between 200 to 1100 nm. The optimization results have been tested again to verify the reliability. The uncertainty analysis of these experiments is less than 10%. The result of the study shows that the conversed power of the solar cells can be increased from 3.877 W to 4.013 W, which has a 3.51% power enhancement! Therefore, the RSM for the optimization of encapulation parameters can improve the quality of encapulation process efficiently.
