摘要
本研究以薄膜太陽能電池技術為基礎，開發薄膜太陽能電池應用於新型臉部辨識系統。藉由兩側LED光源提供照明，因人臉膚色與輪廓差異的反射光，使相對位置的薄膜太陽能電池輸出不同的電壓與電流，並以此作為臉部特徵的判斷依據。本研究藉由精準控制LED不同光強度來提升薄膜太陽能電池應用在臉部辨識上的精準度。根據最後的實驗結果，成功分辨五位不同人的臉部特徵，由此證明薄膜太陽能電池應用於臉部辨識系統是可行的。

We have developed a new face recognition system based on thin-film solar cells that convert the light reflected from the user’s face into electrical signals. The LEDs assembled on both ends of the solar module provide illumination for the user’s face. The correspondence solar cells generate electrical output at varying light intensities caused by diffuse reflection of the individual’s unique 3-diemensional contour and skin color, thus providing highly accurate verification. At the end of this research, the thin-film solar cells not only generate green power but also serve as a sensing device for facial recognition. Based on the final experimental results, we successfully distinguished the facial features of five individuals, thus proving that it is feasible to apply thin-film solar cells to face recognition systems.
