Photovoltaic Property of Dye-Sensitized Solar Cell based on Metal-free Organic Photosensitizers. |
| 초록 |
Dye-sensitized solar cells (DSSCs) have attracted considerable attention on account of their high solar energy-to-conversion efficiencies and low cost processes compared to conventional p-n junction solar cells. Despite potential advantages of their high molar extinction coefficiency, convenient, and customized molecular design for their photophysical and photochemical properties, the organic photo-sensitizer still remain rather limited application field mainly because of their lower conversion efficiencies (2~9%) and stabilities, compared to Ru-dyes. In this work, the DSSCs were fabricated with double electron acceptor metal-free organic photo-sensitizer on the phenothiazine framework that was bridged with thiophene moieties. An organic dye with a single electron acceptor was also synthesized for comparison purposes. |
