초청총설논문 : 염료감응 태양전지 = Invited Review Article : Dye-Sensitized Solar Cell

다국어 초록 (Multilingual Abstract)

Solar cells, converting directly light into electricity, can be categorized by materials comprising solar cells: inorganic-type and organic-type solar cells. Inorganic solar cells are composed of inorganic n-type and p-type materials such as silicon and compound semiconductors, where the structure of inorganic solar cell is typically built by pn junction. For the organic solar cells, there are two types: dye-sensitized solar cell and organic donor-acceptor solar cell. Dye-sensitized solar cell, consisting of nanocrystalline oxide film sensitized with dye molecule, redox electrolyte and metal counter electrode, is consideed as alternative to conventional solar cells due to its high solar-to-electricity conversiton efficiency (ca. 11%) and low cost. In this article, the structure, the operation principle and the recent R&D and industrial trends of dye-sensitized solar cells are discussed.
