Demonstration of high power output from solar concentrator-assisted T25/T240-DL-based DSSC. Photographs of a propeller installed on an electric motor powered by a T25/T240-DL-based DSSC without condenser lens-based solar concentrator (a) before and (b) after light illumination (Here, the propeller did not rotate after light illumination). Photographs of a propeller installed on an electric motor powered by a T25/T240-DL-based DSSC with condenser lens-based solar concentrator (c) before and (d) after light illumination (Here, the propeller rotated very fast after light illumination).
