Abstract
A method for manufacturing a perovskite crystal structure includes preparing a substrate, disposing a stamp having a roll shape on the substrate, injecting a perovskite precursor solution between the substrate and the stamp, and drying the precursor solution to manufacture a perovskite crystal structure. The stamp rolls in a first direction on the substrate, and the precursor solution is continuously crystallized in the first direction between the substrate and the stamp to manufacture the perovskite crystal structure.

A method for manufacturing a perovskite crystal structure, the method comprising:
- preparing a substrate;
- disposing a stamp having a roll shape on the substrate;
- injecting a perovskite precursor solution between the substrate and the stamp;
- and
- drying the precursor solution to manufacture a perovskite crystal structure,
- wherein the stamp rolls in a first direction on the substrate, and
- wherein the precursor solution is continuously crystallized in the first direction between the substrate and the stamp to manufacture the perovskite crystal structure.
An apparatus for manufacturing a perovskite crystal structure, the apparatus comprising:
- a substrate;
- a stamp having a roll shape on the substrate;
- and
- a supply part for supplying a perovskite precursor solution onto an outer circumferential surface of the stamp,
- wherein the stamp rolls from a first region of the substrate to a second region of the substrate, and
- wherein the stamp comprises:
- protrusion portions which are provided on the outer circumferential surface and have loop shapes surrounding the outer circumferential surface;
- and a flat portion between the protrusion portions,
- wherein the protrusion portions are separated from each other in a length direction of the stamp.
A method for manufacturing a crystal structure, the method comprising:
- providing a precursor solution on a substrate;
- and
- drying the precursor solution to manufacture a crystal structure,
- wherein the precursor solution is continuously crystallized from a first region of the precursor solution to a second region of the precursor solution, and
- wherein a single-crystallinity of the crystal structure is adjusted depending on a thickness of the precursor solution.
