Claim 0:
1. A perovskite solar cell (PSC) comprising, in order:
a first layer comprising a conducting material coated glass plate as a substrate;
a second layer comprising copper doped nickel oxide;
a third layer comprising a methylammonium lead iodide (MAPbI3) perovskite;
a fourth layer consisting of N-doped graphene quantum dots;
a fifth layer comprising a fullerene derivative; and
a top layer comprising a conductive layer,
wherein the third layer and the fourth layer are separate layers,
wherein the N-doped graphene quantum dots are present on a surface of the third layer,
wherein the N-doped graphene quantum dots consist of N, C, O, and H,
wherein the perovskite is in the form of crystalline flakes with a mean diameter of 0.1 to 1 μm, and
wherein the third layer is a continuous layer of the crystalline flakes.
