  • See-through-type integrated thin-film solar cell, method of manufacturing the same and method of electrically series connecting unit cells thereof
    Patent number: 8449782
    Abstract: Provided is a method of manufacturing a see-through-type integrated solar cell and a method of manufacturing the same. The method comprises forming a first conductive material being apart and strip patterned on a transparent substrate so that the first conductive material comprises a predetermined space for enabling light to directly pass through the transparent substrate, forming a solar cell (semiconductor) layer, obliquely depositing a second conductive material and etching the solar cell layer using the second conductive material layer as a mask.
    Type: Grant
    Filed: December 13, 2006
    Date of Patent: May 28, 2013
    Assignee: Korea Advanced Institute of Science and Technology
    Inventors: Koeng Su Lim, Seong Won Kwon, Joong Hwan Kwak, Ji Hwan Yang, Sang Il Park, Sang Hwan Kim, Yoo Jin Lee, Jin Koog Shin
  • Integrated thin-film solar cell and method of manufacturing the same
    Patent number: 8168882
    Abstract: Provided are an integrated thin-film solar cell and a method of manufacturing the same. The method comprises forming and patterning a conductive material to be adjacently spaced a predetermined distance apart from each other on a substrate; forming a solar cell (semiconductor) layer on the resultant substrate; obliquely depositing a first transparent conductive material on the solar cell layer; etching the solar cell layer using the first transparent conductive material as a mask; and obliquely depositing a second transparent conductive material on the resultant substrate, and electrically connecting the conductive material with the first transparent conductive material.
