結晶矽太陽能電池片替代關係之決策分析

Decision analysis of crystalline silicon solar cell substitution

指導教授 : 林真如

摘要


隨著全球能源短缺,潔淨再生的能源成為大家關切的研究主題,其中太陽能已逐漸成為重要替代能源之一。但在太陽能電池模組的製造過程中,存在電池片光學的復合損失(recombination loss),以及在封裝過程中所產生電學的不匹配損失(mismatch loss),這兩種損失除了讓太陽能模組產品的轉換效率低落外,對模組封裝廠而言,亦會直接造成銷售利潤下降。本論文研究以模組輸出功率為績效值,分析結晶矽太陽能電池片的最佳供應商及其料件品項,建立電池片供應商遴選替代關係之決策準則。本論文目的為分析多家電池片供應商其材料於模組封裝後輸出功率的異同,研究方法先以變異數分析(ANOVA)檢定輸出功率是否有顯著差異。在拒絕一致性後,接續以Tukey檢定進行材料輸出功率的兩兩比較。在復合損失及不匹配損失的干擾之下,模組投入和產出的功率瓦數並不平衡,造成模組封裝後有不同程度的效率損失。本論文藉由多重比較方法找出輸出功率不具顯著差異的料件品項,做為電池片材料替換的決策準則。研究分析顯示採用本論文所提出之供應商遴選替代準則將有助於減少成本損失並提高利潤,可協助太陽能模組封裝廠提升產業競爭力。

並列摘要


With the shortage of energy, clean and renewable energy becomes a popular research topic. Solar energy is one of the important alternatives. However, there exists optical cell recombination loss and mismatch loss in electricity during the manufacturing and packaging processes of solar modules. These two types of losses would decrease the conversion efficiency of solar modules, and directly reduce the profit of solar module packaging manufacturers. This research studies electrical power output of modules to find the best supplier of crystalline silicon solar cells by investigating their replaceable relationship. The objective of this research is to analyze the similarity of power output of the modules that use the solar cells from different suppliers. Analysis of variance (ANOVA) is first applied to test whether the power output of solar cells are significantly different. If consistency is rejected, Tukey test is then conducted for pairwise comparisons. Under the disturbance of recombination loss and mismatch loss, power input and output are imbalanced which leads to different level of loss in efficiency after module packaging. This research investigates the solar cells with no difference in power output by multiple comparisons and sets up the rule for cell replacement. The results show that the proposed criteria of supplier selection can reduce cost, increase profit, and improve the competitive performance of solar module packaging manufacturers.
