Enhanced Light Harvesting in Dye-Sensitized Solar Cell Using External Lightguide

الملخص EN

An external lightguide (EL) for enhancing the light-harvesting efficiency of dye-sensitized solar cells (DSSCs) was designed and developed.

The EL attached to the exterior of a DSSC photoelectrode directed light on a dye-covered nanoporous TiO2 film (D-NTF) of the photoelectrode.

Experimental tests confirmed that the EL increased the light-harvesting efficiency of a DSSC with an active area of 0.25 cm2 by 30.69%.

Photocurrent density and the power conversion efficiency were also increased by 38.12% and 25.09%, respectively.
