The feasibility of solid‐state dye‐sensitized solar cells as a low‐cost alternative to amorphous silicon cells is demonstrated. Such a cell (see Figure) with a record efficiency of over 4 % under simulated sunlight is reported, made possible by using a new organic metal‐free indoline dye (see Figure) as the sensitizer with high absorption coefficient.
