Enhancement of the efficiency of dye-sensitized solar cell by utilizing carbon nanotube counter electrode

We investigated the performance of dye-sensitized solar cells (DSSCs) by applying carbon nanotubes (CNTs) to the counter electrode using two different methods: screen printing and chemical vapor deposition. When the highly purified and aligned CNTs were used as the counter electrode, a conversion ef...

Description
Summary:We investigated the performance of dye-sensitized solar cells (DSSCs) by applying carbon nanotubes (CNTs) to the counter electrode using two different methods: screen printing and chemical vapor deposition. When the highly purified and aligned CNTs were used as the counter electrode, a conversion efficiency of DSSCs of over 10% was recorded. This CNT-deposited counter electrode shows a higher photoconversion efficiency than CNT-printed and Pt-coated electrodes under the same experimental conditions.
