Title: Graded bandgap perovskite solar cell

Abstract

This disclosure provides systems, methods, and apparatus related to solar cells. In one aspect a solar cell includes a first electrode, a hole transport layer disposed on the first electrode, a first perovskite layer disposed on the hole transport layer, a cationic diffusion barrier disposed on the first perovskite layer, a second perovskite layer disposed on the cationic diffusion barrier, an electron transport layer disposed on the second perovskite layer, and a second electrode disposed on the electron transport layer. The first perovskite layer comprises a different perovskite than the second perovskite layer.
