Photoanode using carbon nanotubes, method of manufacturing the photoanode, and photovoltaic solar cell including the photoanode

Abstract

Provided are a photoanode including: a conductive substrate; carbon nanotubes and a semiconductor formed on the conductive substrate; and a photosensitizer formed on the carbon nanotubes and the semiconductor, and a solar cell including the photoanode. In the photoanode, the conductive carbon nanotubes can be directly formed on the conductive substrate, thereby promoting electron transfer, unlike in a common photoanode with no carbon nanotubes. In particular, densely formed, branched carbon nanotubes can serve as electron transfer channels between semiconductor particles, thereby enabling an effective application to solar cells, etc.

Dependencies are inferred from the claim text.
