염료감응 태양전지용 고분자 전해질막의 총설 = Review on Polymer Electrolyte Membranes for Dye-sensitized Solar Cells

국문 초록 (Abstract)

염료감응형 태양전지는 지속 가능한 에너지원으로서 많은 관심을 받고 있다. 염료감응형 태양전지의 효율과 장기안정성은 전극 물질과 전해질에 의해 크게 영향을 받는데 본 총설에서는 전해질에 초점을 두어 서술하고자 한다. 고분자 전해질막은 염료감응형 태양전지에서 기존의 액체 전해질을 대체하기 위한 대안으로 제시되어 왔다. 기존의 액체 전해질은 높은 효율을 나타낼 수 있지만 장기적인 안정성 문제와 누액 문제로 인해 고분자 전해질막에 관한 관심은 지속적으로 증가하고있으며 매년 이와 관련된 논문들이 활발히 보고되고 있다. 본 총설은 염료감응형 태양전지를 위한 고분자 전해질막의 개념과개발에 대한 간단한 설명을 다루고 있으며 고분자 매트릭스의 개질, 유-무기 가소제 및 이온성 액체와 같은 첨가제의 도입에따른 염료감응형 태양전지의 효율과 전기화학적 특성에 대해서도 최근의 연구들이 정리되어 있다.

다국어 초록 (Multilingual Abstract)

Dye-sensitized solar cells (DSSCs) have attracted great attention as sustainable energy devices. The efficiency and long-term stability of DSSCs are greatly influenced by electrode materials and electrolytes. In this review, we focused on the electrolytes of DSSCs. Polymer electrolyte membranes have been proposed as an alternative to conventional liquid electrolytes in DSSCs. Conventional liquid electrolytes can exhibit a high efficiency, but due to some problems such as poor long-term stability of device and leakage of liquid, much interest in polymer electrolyte membranes continues to rise and the papers on polymer electrolytes membranes have been extensively reported recently. This review covers the concept and development of polymer electrolyte membranes for DSSCs, and discusses the efficiency and electrochemical properties of DSSCs, highlighting the modification of polymer matrix, the introduction of additives such as organic-inorganic plasticizers and ionic liquids.
