LIGHT-TRANSMITTING ELECTRODE HAVING CARBON NANOTUBE FILM, SOLAR CELL, METHOD FOR PRODUCING LIGHT-TRANSMITTING ELECTRODE HAVING CARBON NANOTUBE FILM, AND METHOD FOR MANUFACTURING SOLAR CELL

摘要

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 comprises a step wherein the metal oxide film, which contains oxygen and a metal element belonging to the group 4, 5 or 6 of the periodic table, is vapor deposited on one surface or both surfaces of the carbon nanotube film. The present invention provides a light-transmitting electrode which comprises a light-transmitting substrate and a conductive carbon nanotube film that is formed directly or indirectly on the light-transmitting substrate.
