Abstract
The present invention provides a light-transmitting electrode which has high electrical conductivity and high electron blocking performance. The present invention also provides a solar cell which is capable of achieving high energy conversion efficiency at low cost. The present invention provides a method for producing a light-transmitting electrode that has a light-transmitting substrate, a carbon nanotube film which is formed directly or indirectly on the light-transmitting substrate, and a metal oxide film which is formed directly on the carbon nanotube film. This production method includes vapor depositing the metal oxide film, which contains oxygen and a metal element belonging to the group 4, 5 or 6 of the periodic table, on one surface or both surfaces of the carbon nanotube film. The present invention provides a light-transmitting electrode which includes a light-transmitting substrate and a conductive carbon nanotube film that is formed directly or indirectly on the light-transmitting substrate.
