Thieno[2,3-a]carbazole-based donor-pi-acceptor organic dyes for efficient dye-sensitized solar cells
 
Document Language : English 
Abstract : New donor-pi-acceptor organic dyes K-1 and K-2 containing thieno[2,3-a]carbazole as an electron donor were designed and synthesized for dye-sensitized solar cells (DSCs). Photophysical and electrochemical properties of K-dyes were investigated. DSCs based on K-dyes showed a high conversion efficiency of 6.6-6.7% with a J(sc) of 12.40-12.49 mA cm(-2) and a V-oc of 0.70-0.71 V. The molecular geometry calculation indicated that the existence of thienocarbazole donor in K-dyes enhanced the molecular planarity compared to the carbazole analogue dye MK-3. As a result, DSCs based on K-dyes showed high IPCEs, perhaps due to efficient intramolecular charge transfer and electron injection from excited dye to TiO2 conduction band.
