▎ 摘 要
NOVELTY - The utility model claims a graphite/silicon solar cell, the graphite/silicon solar cell from bottom to top in turn provided with the back electrode, a p-type silicon layer, an n-type silicon layer, an n-type doped graphene-containing layer and a front electrode, graphene oxide doped carrier concentration of not less than 1012 cm 2. A manufacturing comprises the following steps: taking p-type silicon sheet into a chemical etching solution so that the surface structure is formed, and then the etching of a via a diffusion or ion implantation for forming an n-type phosphorus-doped silicon layer, and then the n-type doped graphene is transferred to a doped n-type silicon layer, to make a back electrode on the p-type silicon layer, to make a front electrode on the n-type doped. This utility model of the graphene/silicon solar cell using graphene material can improve the open-circuit voltage of the solar battery, and can reduce the series resistance of the solar cell and improve the output power.
