Disclosed are a solar cell cutting and passivation integrated processing method and a solar cell prepared using the method. The solar cell includes a substrate (1), a front electrode layer (2), a light absorption layer (3) and a back electrode layer (4) from bottom to top. Before laser structured cutting is performed for the back electrode layer (4), a protective layer (5) is disposed on a surface of the back electrode layer (4), and then laser structured cutting is performed for the back electrode layer (4), or the back electrode layer (4) and the light absorption layer (3) simultaneously through the protective layer (5) to obtain a corresponding structured trench (P3) while the protective layer (5) is kept from being cut by laser, and a material of the protective layer (5) is partially molten due to a localized high temperature generated by the laser processing in a laser structured cutting process and infiltrates into an underlying corresponding structured trench (P3). In this method, at the time of performing laser cutting processing, passivation is performed for newly-processed trench at the same time, reducing production costs, saving processing time. Further, the trench edges after cutting are repaired to improve the morphology of the processed trench, improving the stability of the cell and extending the service life of the cell.

In accordance with a method of forming a halide perovskite thin film, a first halide perovskite material is chosen from which a halide perovskite thin film is to be formed. An epitaxial substrate formed from a second halide perovskite material is also chosen.

An optoelectronic device such as a photovoltaic device which has at least one layer, such as an electron transport layer, which comprises a plurality of alternating, oppositely charged layers including metal oxide layers. The metal oxide can be zinc oxide. The plurality of layers can be prepared by layer-by-layer processing in which alternating layers are built up step-by-step due to electrostatic attraction. The efficiency of the device can be increased by this processing method compared to a comparable method like sputtering. The number of layers can be controlled to improve device efficiency. Aqueous solutions can be used which is environmentally friendly. Annealing can be avoided. A quantum dot layer can be used next to the metal oxide layer to form a quantum dot heterojunction solar device.

Provided are a method for manufacturing a perovskite nanocrystal particle light-emitter where an organic ligand is substituted, a light-emitter manufactured thereby, and a light emitting device using the same. A method for manufacturing an organic-inorganic-hybrid perovskite nanocrystal particle light-emitter where an organic ligand is substituted may comprise the steps of: preparing a solution including an organic-inorganic-hybrid perovskite nanocrystal particle light-emitter, wherein the organic-inorganic-hybrid perovskite nanocrystal particle light-emitter comprises an organic-inorganic-hybrid perovskite nanocrystal structure and a plurality of first organic ligands surrounding the organic-inorganic-hybrid perovskite nanocrystal structure; and adding, to the solution, a second organic ligand which is shorter than the first organic ligands or includes a phenyl group or a fluorine group, thereby substitutes the first organic ligands with the second organic ligand. Thus, since energy transfer or charge injection into the nanocrystal structure increases through ligand substitution, it is possible to further increase light emitting efficiency and increase durability and stability by means of a hydrophobic ligand.
