Self-Crack-Filled Graphene Films by Metallic Nanoparticles for High-Performance Graphene Heterojunction Solar Cells

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 junct...

Zusammenfassung: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%).
