Solar cells and methods of making solar cells

Abstract

Embodiments of the present disclosure describe a solar cell comprising a first monolayer and a second monolayer, the first monolayer and the second monolayer forming a monolayer p-n lateral heterojunction with an atomically sharp interface; and a substrate, the substrate and the monolayer p-n lateral heterojunction forming a solar cell. Embodiments of the present disclosure further describe a method of making a solar cell comprising growing a first monolayer on a first substrate; growing a second monolayer on the first substrate sufficient to form a monolayer p-n lateral heterojunction with an atomically sharp interface; and transferring the monolayer p-n lateral heterojunction from the first substrate to a second substrate sufficient to form a solar cell.
