FABRICATION METHOD FOR BACK CONTACT SOLAR CELL

摘要

The present invention discloses a back contact solar cell comprising: a first conductive type semiconductor substrate having a textured front surface and a textured rear surface; an oxide layer formed on the front surface of the substrate; at least one first conductive type semiconductor region and second conductive type semiconductor region formed in an alternating pattern at predetermined intervals on the rear surface of the substrate; an oxide layer formed on the remaining rear surface of the substrate except for the first conductive type semiconductor region and the second conductive type semiconductor region; and electrodes formed on each of the first conductive type semiconductor region and the second conductive type semiconductor region.
