Abstract

Graphene, with cracks filled with gold nanoparticles, is grown by chemical vapor deposition on a Cu substrate. The crack-filled graphene not only exhibits superior electrical properties but also forms a better junction with other semiconductors. A high-quality crack-filled graphene/Si Schottky junction solar cell is achieved, demonstrating the highest fill factor (0.79) and best efficiency (12.3%).

Keywords: Schottky solar cells; chemical vapor deposition (CVD) graphene; metallic nanoparticles; self-crack-filled.
