Patent number: 9136414Abstract: Provided are a back sheet for a solar cell module, and a solar cell module comprising same. The back sheet for a solar cell module comprises: a heat-dissipating metal layer; an upper anticorrosion layer formed on the upper surface of said heat-dissipating metal layer; a lower anticorrosion layer formed on the lower surface of said heat-dissipating metal layer; and a surface layer formed on said upper anticorrosion layer and adhered to a charging sheet of the solar cell module. The back sheet for a solar cell module according to the present invention has superior heat-dissipating properties and thus may efficiently dissipate (discharge) heat generated in a solar cell, thereby increasing the amount of power generation (photoconversion efficiency) of the solar cell. In addition, the back sheet of the present invention is inexpensive and may improve adhesive force and the like.Type: GrantFiled: May 17, 2012Date of Patent: September 15, 2015Assignee: Youl Chon Chemical Co., LTD.Inventors: Han Jun Kang, Sung Ho Lee, Jin Ho Kim

Patent number: 8980413Abstract: Cell packaging according to one embodiment of the present invention comprises: a base film layer; and a print layer provided beneath or on the base film layer, and including a binder resin and carbon black. The base film layer or print layer of the cell packaging is partially removed by means of laser irradiation to expose the layer under same. Therefore, according to the cell packaging of the invention, a wide range of shapes or logos, etc. can easily be externally displayed so as to be discernible by means of laser irradiation. By thus imparting discernibility and externality to the cell packaging, a labeling process for attaching a separate label to the cell packaging can be excluded.Type: GrantFiled: September 15, 2010Date of Patent: March 17, 2015Assignee: Youl Chon Chemical Co., Ltd.Inventors: Han Jun Kang, Hee Sik Han, Woo Sic Jung, Sung Ho Lee, Jong Woon Yoon, Ji Hee Kim, Sang Min Lee

Publication number: 20110212361Abstract: Provided is a cell packaging material having a layered structure of one or more layers, wherein at least one layer includes a flame retardant, a coating layer imparted with flame resistance, or both. In the cell packaging material, a cell itself does not include any flame resistant film or flame retardant. Therefore, it is possible to provide a cell with flame resistance while not increasing the cell volume or not affecting the cell operation.Type: ApplicationFiled: November 3, 2009Publication date: September 1, 2011Applicant: YOULCHON CHEMICAL CO., LTD.Inventors: Young-Hee Kim, Han Jun Kang, Hee Sik Han, Jong Woon Yoon
