Abstract

Embodiments of the present disclosure provide for solar cells including an organometallic halide perovskite monocrystalline film (see FIG. 1.1 B), other devices including the organometallic halide perovskite monocrystalline film, methods of making organometallic halide perovskite monocrystalline film, and the like.

First claim

We claim:

1. A solar cell, comprising:
a substrate;
an organometallic halide perovskite monocrystalline film having a (001) orientation grown on the substrate by cavitation-triggered asymmetric crystallization, wherein the organometallic halide perovskite monocrystalline film includes methylammonium lead bromide (MAPbBr 3 ); and
a metal layer disposed on the organometallic halide perovskite monocrystalline film.

2. The solar cell of claim 1 , wherein the substrate includes one or more of indium tin oxide (ITO)-coated glass, fluoride coated tin oxide (FTO), silicon, and metal coated silicon.

3. The solar cell of claim 1 , wherein the metal layer is one or more of Au, Ag, and Cu.

4. The solar cell of claim 1 , wherein the organometallic halide perovskite single crystal film has a thickness of about 300 nm to 50 μm and wherein the metal layer has a thickness of about 50 nm to 200 nm.

5. A device, comprising:
a substrate, wherein the substrate includes one or more of indium tin oxide (ITO)-coated glass, fluoride coated tin oxide (FTO), silicon, and metal coated silicon;
an organometallic halide perovskite monocrystalline film having a (001) orientation grown on the substrate by cavitation-triggered asymmetric crystallization, wherein the organometallic halide perovskite monocrystalline includes methylammonium lead bromide (MAPbBr 3 ); and
a metal layer disposed on the organometallic halide perovskite monocrystalline film, wherein the metal layer includes one or more of Au, Ag, and Cu.

6. The solar cell of claim 1 , wherein an adhesion force between the substrate and organometallic halide perovskite monocrystalline film includes electrostatic interactions, Van der Waals forces, or a combination thereof.
