Synthesis and photovoltaic properties of novel organic sensitizers containing indolo[1,2-f]phenanthridine for solar cell
摘要:
Organic dyes containing indolo[1,2-f]phenanthridine unit are a promising new class of sensitizers for dye-sensitized solar cells, as a result of their broad and intense visible absorptions. Under standard global AM 1.5 solar condition, the JK-61 sensitized cell gave a short circuit photocurrent density (J(sc)) of 15.81 mA cm(-2), an open circuit voltage (V-oc) of 0.73 V, a fill factor of 0.72, corresponding to an overall conversion efficiency of 8.34%.
