    摘要: The present invention provides a method for manufacturing a solar cell capable of suppressing volatilization of selenium and deformation of a substrate during a manufacturing process. According to the present invention, the method for manufacturing the solar cell comprises the steps of: providing a substrate; forming a rear electrode on the substrate; forming a precursor film for a light absorption film on the rear electrode; forming a light absorption film by progressing a crystallization process for the precursor film for the light absorption film; forming a buffer film on the light absorption film; forming a window film on the buffer film, and forming an anti-reflection film on the window film; and partially patterning the anti-reflection film, and forming a grid electrode in a patterned area. Said precursor film for the light absorption film includes Cu—Zn—Sn—S (Cu2ZnSnS4), CuInSe2, CuInS2, Cu(InGa)Se2, or Cu(InGa)S2. Further, a Cu—Zn—Sn—S (Cu2ZnSnS4) precursor film, a CuInSe2 precursor film, a CuInS2 precursor film, and a Cu (InGa)Se2 precursor film or a Cu(InGa)S2 precursor film can have a multi-layer structure of each component or a single-layer structure having compounds of the components. Said crystallization step for the precursor film is progressed through an electron-beam irradiation process.

    摘要: Disclosed herein is a safety outlet. The safety outlet includes a casing having at least one hole into which a pin of a plug is inserted; and at least one drain pipe forming a drain channel for independently communicating the at least one hole and the outside of the casing; wherein the drain channel provided in the at least one drain pipe each serves as drain passage separated from each other, and the drain pipe is partitioned so as to maintain sealing between inside of the casing and the drain channel, wherein a contact portion connected to a power terminal arranged outside of the at least one drain pipe is provided in the at least one drain pipe.
