Abstract

[ $CdS_{0.46}Se_{0.54}$ ] single crystal was grown by a sublimation method. The crystal structure and the temperature dependence of carrier density and mobility of $CdS_{0.46}Se_{0.54}$ single crystal were studied. Heterojunction solar cells of $n-CdS_{0.46}Se_{0.54}/p-Cu_{2-X}S_{0.46}Se_{0.54}$ were fabricated by the substitution reaction. The spectral response, the J-V characteristics and the conversion efficiency of the $n-CdS_{0.46}Se_{0.54}/p-Cu_{2-X}S_{0.46}Se_{0.54}$ heterojunction solar cells were studied. The open-circuit voltage, short-circuit density, fill factor and conversion efficiency of $n-CdS_{0.46}Se_{0.54}/p-Cu_{2-X}S_{0.46}Se_{0.54}$ heterojunction solar cells under $80mW/cm^2$ illumination were found to be 0.48V, $21mA/cm^2$, 0.75 and 9.5%, respectively.

승화방법에 의해 $CdS_{0.46}Se_{0.54}$ 단결정을 성장하여 결정구조를 조사하고, Van der Pauw 방법으로 Hall effect를 측정하여 carrier density의 온도 의존성과 mobility의 온도 의존성을 조사하였다. 성장된 $CdS_{0.46}Se_{0.54}$ 단결정을 치환반응하여 $n-CdS_{0.46}Se_{0.54}/p-Cu_{2-X}S_{0.46}Se_{0.54}$ 이종접합 태양전지를 제작하였다. Spectral response, 전류-전압특성 및 전력변환 효율을 조사하여 그 결과로부터 개방전압은 0.48V, 단락 전류 밀도는 $21mA/cm^2$, fill factor와 전력변환효율은 각각 0.75와 9.5%를 얻었다.
