Abstract
A method includes forming a barrier layer on a substrate, removing a portion of the barrier layer to yield a patterned barrier layer and an exposed portion of the substrate within a hole in the patterned barrier layer, forming a first portion of a perovskite on the patterned barrier layer and a second portion of the perovskite on the exposed portion of the substrate, and removing the patterned barrier layer, thereby removing the first portion of the perovskite.
