Abstract

Using poly(ethylene oxide) (PEO) as a polymer host, poly(ethylene glycol) (PEG) as a plasticizer, potassium iodide and iodine as sources of $I^-/{I_3}^-$ PEO-PEG-KI/$I_2$ polymer gel electrolytes were prepared. Based on the polymer gel electrolytes, solid-state dye-sensitized solar cell(DSSC)s were fabricated. The content of PEG in the electrolyte was changed from 0 to 85%. The electrolyte showed self-supporting form through whole range of the PEG content. As the PEG content increased, the ionic conductivity and ${I_3}^-$ diffusivity increased and the light-to electrical energy conversion efficiency increased under irradiation of 100 $mWcm^{-2}$ simulated sunlight.

염료감응형 태양전지를 위한 고분자 전해질막을 제조하였다. 고분자물질로는 Poly(ethylene oxide) (PEO)를 사용하였으며, 가소제로서 poly(ethylene glycol) (PEG)를 첨가하였고, 전해질염 및 $I^-/{I_3}^-$의 공급원으로서 KI 및 $I_2$를 첨가하여 고분자 전해질막을 제조하였으며, 이와 같은 고분자 전해질막을 바탕으로 염료감응형 태양전지를 제조하였다. 고분자 전해질 내의 가소제로서의 PEG 함량은 0%에서 85%의 범위로 변화하였다. 이러한 PEG 함량 전 구간에서 고분자 전해질막은 그 형태를 자체적으로 유지하는(self supporting) 완벽한 고체 전해질막의 형태로 제조되었다. PEG 함량이 증가하면서 전해질막을 통한 이온전도도와 ${I_3}^-$ 이온의 확산도계수는 증가하였다. 염료감응형 태양전지에 있어서는 고분자 전해질막 내의 PEG 함량이 증가하면서 그 효율이 증가함을 볼 수 있었다.
