CIGS太陽能電池製程之模擬研究
Numerical Investigation into the process for CIGS solar cells
摘要
本研究主要探討銅銦鎵硒(Copper Indium Gallium Selenium ,簡稱CIGS)薄膜太陽能電池在真空塗佈製程中之氣體分布、熱量傳導與輻射熱傳情形。由於此類薄膜太陽能電池在硒化製程中之沉積物會產生分佈不均勻之現象，所以希望利用電腦數值模擬方法，亦即所謂的計算流體動力學方式(Computational Fluid Dynamics;CFD)建立銅銦鎵硒薄膜太陽能電池在硒化製程的數值模擬技術，作為未來銅銦鎵硒太陽能電池製程技術改造與效率提升之設計工具。研究的結果顯示，模擬與實驗的誤差約為15%，而模擬出來的升溫趨勢與實驗相近，故證實了本研究模擬之可行性。

The flow filed, heat conduction, and heat radiation effects on a vacuum-based manufacturing process of the CIGS thin film photovoltaic cells inside a chamber are investigated in this research. Due to the non-uniform thickness of the CIGS films on some substrates after the deposition, the computational fluid dynamics approach is used to investigate the selenization process. The purpose of using computational fluid dynamics is to study the temperature effect and the flow filed inside the chamber during the selenization, and to provide some possible modifications to improve the manufacturing efficiency. The computed temperature shows a good agreement with the experimental data and the error is about 15%.The time dependent temperature variations inside the chamber are similar to the experimental measurement. The results demonstrate the possibility of using computational fluid dynamics to improve the manufacturing process of the CIGS cells.
