▎ 摘　　要

NOVELTY - The battery has a rear electrode (1), a P-type silicon layer (2), a N-type silicon layer (3), a N-type doped graphene-containing layer (4) and a front electrode (5) that are connected with each other. Carrier concentration of the N-type doped graphene-containing layer is greater than 1012 cm 2. USE - Graphene/silicon solar battery. ADVANTAGE - The battery increases open-circuit voltage and output power and reduces series resistance. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a graphene/silicon solar battery.
