文摘

A new type of organic sensitizers incorporating a planar amine unit have been synthesized and demonstrated to be a highly efficient sensitizers, showing evidence of lateral interactions on the TiO₂ surface. Under standard global air mass 1.5 solar conditions, the JK-98 sensitized cell gave a short circuit photocurrent density (J_sc) of 16.78 mA cm^鈥?, an open-circuit voltage (V_oc) of 0.745 V, and a fill factor (ff) of 0.70, corresponding to an overall conversion efficiency (畏) of 8.71%.
