Advances in Flexible Optoelectronics Based on Chemical Vapor Deposition-Grown Graphene

摘要

Graphene shows great potential for flexible optoelectronic devices owingto its unique 2D structure and excellent electronic, optical, and mechanicalproperties. Chemical vapor deposition (CVD) is the most promising methodfor fabricating large-area and high-quality graphene films at an acceptablecost; therefore enormous efforts have been attempted to investigate theflexible optoelectronic devices based on CVD-grown graphene. Here, recentadvances and significant development of CVD-grown graphene towardsflexible optoelectronics including photodetectors, organic solar cells, andlight-emitting diodes are reviewed. Insight into the challenges of improvementof optoelectronic properties, work function tuning, as well as interfacialcontrol of CVD-grown graphene for high-performance devices is provided. Inparticular, the availability to fabricate large-area devices on the flexible substratesis discussed, which is crucial to drive the practical use of CVD-growngraphene for future wearable optoelectronics.
