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 ( V oc ), short‐circuit photocurrent‐density value ( J sc ), and the fill factor, which also show barely no decline (see picture).
