A Light-Resistant Organic Sensitizer for Solar-Cell Applications

Finely tuned: A stable dye‐sensitized solar cell that contains a molecularly engineered organic dye has been prepared. The efficiency of the cell remains at 90 % after 1000 h of light soaking at 60 °C. The remarkable stability of the cell is also reflected in the open‐circuit voltage value (Voc), sh...

Description
Summary:	Finely tuned: A stable dye‐sensitized solar cell that contains a molecularly engineered organic dye has been prepared. The efficiency of the cell remains at 90 % after 1000 h of light soaking at 60 °C. The remarkable stability of the cell is also reflected in the open‐circuit voltage value (Voc), short‐circuit photocurrent‐density value (Jsc), and the fill factor, which also show barely no decline (see picture).
