Disclosed are a hybrid structure using a graphene-carbon nanotube and a perovskite solar cell using the same. The hybrid structure includes a graphene-carbon nanotube formed by laminating a second graphene coated with a polymer on an upper surface of a first graphene coated with a carbon nanotube. The perovskite solar cell includes: a substrate; a first electrode formed on the substrate and including a fluorine doped thin oxide (FTO); an electron transfer layer formed on the first electrode and including a compact-titanium oxide (c-TiO); a mesoporous-titanium oxide (m-TiO) formed on the electron transfer layer; a perovskite layer formed on the m-TiOand including a perovskite compound; and a graphene-carbon nanotube hybrid structure formed on the perovskite layer.

Disclosed is a bus stop using a large-scale perovskite solar cell in which a perovskite solar cell is prepared using a hybrid structure including a graphene-carbon nanotube. The bus stop includes a body unit fixed to the ground to maintain the overall shape, a solar cell unit for producing electrical energy from sunlight, and an energy storage system (ESS) for storing the electrical energy produced by the solar cell part.
