SOLAR CELL AND METHOD FOR MANUFACTURING THE SAME |
摘要 |
A solar cell is discussed, and the solar cell includes: a semiconductor substrate; a tunneling layer on a surface of the semiconductor substrate; a buffer layer on the tunneling layer, wherein the buffer layer is a separate layer from the tunneling layer and includes an intrinsic buffer portion, and wherein at least one of a material, a composition and a crystalline structure of the buffer layer is different from those of the tunneling layer; a conductive type region on the tunneling layer, and including a first conductive type region having a first conductive type and a second conductive type region having a second conductive type; and an electrode connected to the conductive type region. The buffer layer is positioned adjacent to the tunneling layer and is apart from the electrode. |
