چکیده انگلیسی
Five functionalized organic dyes (H6-10) containing a phenanthroimidazole unit as an electron donor were synthesized and characterized for use in dye-sensitized solar cell (DSSC) applications. Under standard global AM 1.5 solar conditions, the DSSCs based on dye H6 displayed the best performance, with an incident photon-to-current conversion efficiency (IPCE) exceeding 70% at wavelengths of 400-530Â nm, a short-circuit photocurrent density of 10.98Â mAÂ cmâ2, an open-circuit voltage of 0.68Â V, a fill factor of 0.69, and an overall conversion efficiency of 5.12%. This efficiency is â¼94% of that for JK2 cells (5.46%) and â¼72% of that for N719 cells (7.07%) under the same conditions.
