Abstract
This disclosure provides a back contact solar cell and a method for manufacturing a back contact solar cell. In one example, a back contact solar cell includes a silicon substrate having first regions and second regions alternately distributed on a back surface of the silicon substrate, and a first doped semiconductor layer formed on a first region on the back surface of the silicon substrate. A groove structure concaving inward the silicon substrate relative to a surface of the first region is formed on a second region. An end portion of the first doped semiconductor layer adjacent to the second region is arranged in a suspended manner.
