Abstract
The perovskite solar cell (PSC) includes a first layer containing a conducting material coated glass plate as a substrate, a second layer containing copper doped nickel oxide, a third layer containing a perovskite, a fourth layer containing nitrogen (N)-doped graphene quantum dots, a fifth layer containing phenyl-C61-butyric acid methyl ester and a top layer including conductive layer. A method for producing the perovskite solar cell is also discussed.
