  • Publication number: 20140069498
    Abstract: Provided is a solar cell, including: a semiconductor substrate having a p-n junction; an antireflection film formed on at least one side of the semiconductor substrate; first electrodes formed on the antireflection film; and second electrodes covering the first electrodes, wherein only the first electrodes selectively penetrate the antireflection film and is thus connected with the semiconductor substrate by a punch through process.

  • Publication number: 20140014173
    Abstract: Provided are a solar cell and a method for manufacturing the same, and more particularly, a solar cell for forming a selective emitter structure and a surface texture using dry plasma etching at the same time, and a method for manufacturing the same. The solar cell includes a silicon semiconductor substrate; an emitter doping layer having a surface, which is textured by a texturing process on an upper portion of the silicon semiconductor substrate and selectively doped; an anti-reflective film layer formed on a front of the substrate; a front electrode accessing to the emitter doping layer by penetrating the anti-reflective film layer; and a rear electrode accessing to a rear of the silicon semiconductor substrate.

  • Publication number: 20140017847
    Abstract: Provided is a method of manufacturing a solar cell, wherein a solar cell is manufactured by combining a damage removal etching process, a texturing process and an edge isolation process. The method is advantageous in that RIE and DRE are conducted, and then DRE/PSG and/or an edge isolation removal process are simultaneously conducted, so that the movement of a substrate (that is, a wafer) is minimized, thereby reducing the damage rate of the substrate.

  • Patent number: 7094407
    Abstract: The present invention relates to a fusion peptide, in which a self cell-penetrating Tat peptide having a self penetrating signal is bound to a human Type-I collagen C-terminal derived peptide, a preparation thereof, and a skin anti-aging cosmetic composition comprising the same. Since the fusion peptide, in which the Tat peptide is bound to the human Type-collagen C-terminal derived peptide is highly stable and has a superior skin absorption capability, the present invention provides a skin anti-aging agent having superior synthesis of collagen and hyaluronic acid, anti-aging effects, and improved durability of the effects.

  • Patent number: 7060673
    Abstract: The present invention relates to a fusion peptide wherein a self cell-penetrating Tat peptide having a self penetrating signal is bound to a human parathyroid hormone-derived peptide, a preparation thereof, and a skin slimming cosmetic composition comprising the same. Since the fusion peptide wherein the Tat peptide is bound to the human parathyroid hormone-derived peptide has high stability and superior skin absorption, the present invention provides a skin slimming agent having superior lipolysis effects and improved durability of the effects.

  • Patent number: 7001744
    Abstract: Disclosed is a novel vaccine against Escherichia coli (E. coli) responsible for urinary tract infections. The vaccine is a recombinant chimeric protein which is prepared by linking by genetic recombination a gene encoding an antigenic determinant of uropathogenic E. coli to a CTXA2B gene encoding nontoxic A2 and B subunits of Vibrio cholerae cholera toxin (CTX) or a LTXA2B gene encoding nontoxic A2 and B subunits of E. coli heat-labile enterotoxin, wherein a translation product of the CTXA2B or LTXA2B gene serves as an immunogenic adjuvant stimulating mucosal immune responses, expressing the resulting recombinant gene in E. coli, and isolating and purifying an expressed recombinant fusion protein. The recombinant chimeric protein is useful as an oral vaccine with mild side effects and excellent vaccination efficiency against uropathogenic E. coli.
