Experimental determination of the light-trapping-induced absorption enhancement factor in DSSC photoanodes

Beilstein Journal of Nanotechnology, 2015
For dye-sensitized solar cells (DSSC), the fundamental process that determines the maximum short-circuit current is the absorption of light. In such devices, this is produced by the concurrent phenomena of light absorption by dye molecules and light ...
