Abstract

Dye-sensitized solar cells (DSSCs) were fabricated using graphene-coated Al₂O₃ (GCA)-TiO₂ nanocomposite electrodes. The GCA-TiO₂ pastes were prepared by simply blending the GCA particles with TiO₂ particles without any complex treatments. The DSSC with 1wt.% GCA-TiO₂ exhibited much better overall energy conversion efficiency, when compared to the DSSCs with TiO₂ alone and with carbon nanotube-TiO₂. It can be attributed to efficient electron transport through the GCA-TiO₂ to the transparent conducting oxide, resulting in significantly enhanced electron lifetime.
