    Abstract: Disclosed is a method of preparing a solid electrolyte, which includes (a) preparing a solid electrolyte precursor slurry by subjecting a mixed solution including a metal precursor solution, containing a lanthanum precursor, a zirconium precursor and an aluminum precursor, a complexing agent, and a pH controller to coprecipitation, (b) preparing a solid electrolyte precursor by washing and drying the solid electrolyte precursor slurry, (c) preparing a mixture by mixing the solid electrolyte precursor with a lithium source, and (d) preparing an aluminum-doped lithium lanthanum zirconium oxide (LLZO) solid electrolyte by calcining the mixture, and which is also capable of adjusting the aluminum content of a starting material to thus control sintering properties and of adjusting the composition of a precursor and a lithium source to thus control the crystal structure, thereby improving the ionic conductivity of the solid electrolyte. In addition, a method of manufacturing an all-solid-state lithium secondary battery, including a solid electrolyte having improved ion conductivity, can be provided using the method of preparing the solid electrolyte.

    Abstract: One embodiment of the present invention relates to a method for manufacturing solar cells having a nano-micro composite structure on a silicon substrate and solar cells manufactured thereby. The technical problem to be solved is to provide a method for manufacturing solar cells and solar cells manufactured thereby, the method being capable of forming micro wires in various sizes according to the lithographic design of a photoresist and forming nano wires, which have various sizes and aspect ratios, by adjusting the concentration of a wet etching solution and immersion time. To this end, the present invention provides a method for manufacturing solar cells and solar cells manufactured thereby, the method comprising the steps of: preparing a first conductive semiconductor substrate having a first surface and a second surface; patterning a photoresist on the second surface of the first conductive semiconductor substrate such that the plane form of the photoresist becomes a form in which multiple horizontal lines and multiple vertical lines intersect each other; electrolessly etching the semiconductor substrate so as to form a micro wire having a width of 1-3 μm and a height of 3-5 μm in a region corresponding to the photoresist and to form multiple nano wires having a width of 1-100 nm and a height of 1-3 μm in a region not corresponding to the photoresist; doping the micro wire and nano wires with a second conductive impurity by using POCl3; forming a first electrode on the first surface of the semiconductor substrate; and forming a second electrode on the micro wire, wherein the efficiency of the solar cells is 10-13%, the efficiency being the ratio of output to incident light energy per unit area.
