Method of manufacturing metal oxide crystal and method of fabricating substrate for solar cell

摘要

Provided are a method of manufacturing a metal oxide and a substrate for a solar cell. The method of manufacturing the metal oxide according to the inventive concept includes mixing a metal precursor material, a basic material, amphiphilic molecules and distilled water to prepare a metal precursor solution, performing a first heat treatment with the metal precursor solution to form a metal oxide, and performing a second heat treatment with the metal oxide to form a pair of metal oxide disks having a single crystalline structure. A pair of zinc oxide disks includes a first disk, and a second disk separated from the first disk in a perpendicular direction to the first disk.

1. A method of manufacturing a metal oxide crystal, the method comprising:
mixing a metal precursor material, a basic material, amphiphilic molecules and distilled water to prepare a metal precursor solution; performing a first heat treatment with the metal precursor solution to form a metal oxide; and performing a second heat treatment with the metal oxide to form a pair of metal oxide disks having a single crystalline structure, wherein the pair of metal oxide disks include a first disk, and a second disk separated from the first disk in a perpendicular direction to the first disk, wherein the metal precursor solution comprises: a first inner layer formed by hydrophobic functional groups of the amphiphilic molecules; a first outer layer formed by hydrophilic functional groups of the amphiphilic molecules; a second inner layer formed by hydrophobic functional groups of the amphiphilic molecules, the second inner layer facing the first inner layer; a second outer layer formed by hydrophilic functional groups of the amphiphilic molecules, the first and second inner layers being disposed between the first and second outer layers; first metal complex ions on the first outer layer; and second metal complex ions on the second outer layer, the first and second outer layers being disposed between the first and second metal complex ions.
