▎ 摘　　要

NOVELTY - A platinum-graphene grown network/silicon dioxide/n-silicon heterojunction material comprises n-type silicon provided in silicon oxide layer substrate and platinum-graphene grown network nanoparticles, where the lower n-type silicon substrate is provided with a titanium/gold metal electrode. USE - Platinum-graphene grown network/silicon dioxide/n-silicon heterojunction material. ADVANTAGE - The heterojunction material has improved fill factor and increased photoelectric conversion efficiency, and can be prepared in simple and cost effective manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing platinum-graphene grown network/silicon dioxide/n-silicon heterojunction material.
