Dye-sensitized solar cell based on indirect charge transfer

Abstract

A dye-sensitized solar cell that includes an electrode having a semiconductor nanoparticle layer dispersed on a transparent conductive substrate, a plurality of semiconductor nanofibers dispersed on the nanoparticle layer, a first light absorption material is attached to the plurality of semiconductor nanofibers in which the first light absorption material having a first light absorption bandwidth, and a second light absorption material deposited on the light absorption material of the plurality of semiconductor nanofibers, the second light absorption material having a second light absorption bandwidth complementary to the first light absorption bandwidth, a counter electrode includes a metal-coated transparent conductive substrate, and an electrolyte in contact with the near-infrared light absorption material and the counter electrode.
