Fabrication and Characterization of Dye-Sensitized Solar Cells Based on Rhodamine Dyes Choi, Kang-Hoon; Jung, Hye-In; An, Byeong-Kwan;
Rhodamine B (RhB) was utilized as a dye sensitizer for dye-sensitized solar cells (DSSCs) and its photovoltaic property was examined under the illumination of AM 1.5 G, . DSSCs based on RhB exhibited typical photovoltaic properties with an open-circuit voltage () of 0.34 V, a short-circuit current () of , a fill factor (FF) of 50%, and a conversion efficiency (PCE) of 0.26%. In order to further improve the photovoltaic properties of RhB-based DSSCs, the effect of (i) incorporating a strong electron-donating NCS unit into the RhB molecular backbone, (ii) combining a bis-negatively charged zinc complex anion (, dmit=di-mercapto-dithiol-thione) with the amine cation of RhB, (iii) co-adsorbing RhB dyes with chenodeoxycholic acid (CDCA) molecules onto porous electrodes, was investigated and discussed.
