Abstract

The present invention relates to a perovskite optoelectronic device and a manufacturing method therefor. The present invention allows manufacture of a perovskite optoelectronic device with high efficiency at a low cost, as well as improving the electrical conductivity of a carbon nanotube electrode, by laying graphene oxide over conventional carbon nanotubes and may also be applied to a flexible device.
