Abstract
A photovoltaic cell is provided, including a substrate having a front surface with metal and non-metal pattern regions, first and second pyramid structures in each metal pattern region, third and fourth pyramid structures in each non-metal pattern region, a first tunneling layer and a first doped conductive layer on a portion of the front surface in a respective metal pattern region, and a second tunneling layer and a second doped conductive layer on a rear surface of the substrate. A dimension of a bottom portion of each first pyramid structure is greater than that of each second pyramid structure. A dimension of a bottom portion of each third pyramid structure is greater than that of each fourth pyramid structure. An area proportion of the first pyramid structures in the metal pattern region is greater than that of the third pyramid structures in a respective non-metal pattern region.
