The present invention provides a hetero-junction silicon solar cell comprising a crystalline silicon substrate and a passivation layer that is formed on the crystalline silicon substrate and is doped with impurities. | 06-18-2009 |
20110017258 | SOLAR CELL AND FABRICATION METHOD THEREOF - A back contact solar cell comprises a first dopant diffusion part and a second dopant diffusion part formed on a rear surface of an n-type semiconductor wafer with a predetermined distance formed therebetween by a diffusion prevention part for ensuring no contact with each other and suppressing the diffusion of dopant; and an electrode configured of an anode and a cathode each connected to the first dopant diffusion part and the second dopant diffusion part. According to the present invention, the back contact solar cell is capable of preventing light loss and improving its efficiency by forming an electrode to be positioned on a rear surface of a semiconductor wafer through a simple process and by simultaneously implementing an anode electrode and a cathode electrode on the semiconductor wafer without having a grid electrode restricting incidence of sunlight. | 01-27-2011 |
20150380575 | BACK CONTACT SOLAR CELL AND FABRICATION METHOD THEREOF - The present invention discloses a back contact solar cell. The back contact solar cell includes a semiconductor substrate having a front surface and a rear surface; and a first conductive type semiconductor region having a first conductive type and a second conductive type semiconductor region having a second conductive type, the first conductive type semiconductor region and the second conductive type semiconductor region being disposed with an interval on the rear surface of the semiconductor substrate. In addition, the rear surface of the semiconductor substrate has a texturing structure at the interval between the first conductive type semiconductor region and the second conductive type semiconductor region. | 12-31-2015 |
