本研究分為三個主題，第一個主題為使用濺鍍前驅層後硒化方式製作CIGS電池的吸收層。濺鍍前驅層的方式使用共濺鍍，目的為改善分層濺鍍可能會遇到的問題，包括薄膜的不均勻和硒化過程中過於劇烈的相變化等，並兼顧適當的Ga深度分佈梯度和MoSe2的厚度。本研究對於CIGS薄膜的結晶性、成分、載子生命週期等性質進行分析，且這些性質皆具有一定程度的表現。

第二個主題為使用Matlab發展出一套能夠對太陽能電池的J-V曲線進行擬合的程式。本研究使用基因演算法進行擬合，該演算法能夠在龐大的解空間中迅速地找到優良的解。此外，該程式兼顧精確性和便利性，並適用於多組數據的自動連續多次擬合。

第三個主題為探討AOI對於電池性能的影響，並將結果運用在BIPV的應用上。本研究利用實際測量和模擬的方式，試著了解Jsc、J-V曲線、EQE等電池參數和AOI的關係。此外，本研究製作出一套電池性能模擬程式，能夠計算電池在不同時間、地點、擺放角度所接收到的輻照度，並根據輻照度計算出該情況的電池性能。

There are three subjects in this study. The first subject is fabrication of CIGS absorbers by sputtering and selenization. Precursors were deposited by co-sputtering in order to overcome problems of sequentially sputtering, such as inhomogeneity in films and dramatic phase evolution during selenization. Moreover, we tried to achieve appropriate Ga gradient and thickness of MoSe2. The material properties of CIGS films were characterized, such as crystallinity, composition and carrier lifetime, and these properties are close to the level of regular CIGS films showed in past publications.

The second subject is focusing on the development of Matlab program for cell’s light J-V curve fitting. We use genetic algorithm to carry out curve fitting, and this algorithm can find high-quality solutions in a large search space in a short time. Furthermore, the program is accurate and convenient to use, and is good at handling many curves and doing curve fitting many times automatically.

The third subject is investigating the effects of AOI on cell performance, and using the results in the application of BIPV . We tried to recognize the correlation between Jsc, J-V curve, EQE and AOI by experiments and simulation. Moreover, we construct a program that can do simulation of irradiance received by cells in different time, location, orientation, and use irradiance to calculate cell performance.
