  • METHOD OF FABRICATING A DIFFERENTIAL DOPED SOLAR CELL
    Publication number: 20130288421
    Abstract: A method of fabricating a differential doped solar cell is provided. The method comprises the steps of (a) providing a light doped semiconductor substrate; (b) forming a heavy doped layer having the same type of dopant used in step (a) on a front surface of the semiconductor substrate; and (c) forming an emitter layer having a different type of dopant used in step (a) on a surface of the heavy doped layer to constitute a p-n junction with the heavy doped layer.
    Type: Application
    Filed: April 16, 2013
    Publication date: October 31, 2013
    Applicant: BIG SUN Energy Technology Incorporation
    Inventors: Chi-Hsiung CHANG, Kuan-Lun CHANG, Hung-Yi CHANG, Yi-Min PAN, Jun-Min WU, Ying-Yen CHIU
