Abstract

Photodetectors (PDs) based on organic-inorganic hybrid materials such as graphene and perovskites have recently emerged at the forefront of the research in optoelectronic devices. Despite the remarkable progress in the performance of optoelectronic devices based on hybrid materials, some aspects such as stability have so far not been thoroughly addressed. This paper serves to demonstrate a fully inkjet-printed PD fabricated by hybrid perovskite (CH3NH3PbClx-3I3) layer between the two graphene electrodes as graphene/perovskite/graphene (GPG) heterostructure. The fully inkjet-printed GPG PD is found to be effective for the visible light region, which can be attributed by the high uniformity and low defects of the printed materials. Thus, the GPG PD achieves a high responsivity of 0.53 A/W. Fully inkjet-printed hybrid perovskite PD demonstrated in this paper unveils the facile, potentially large-scale and cost-effective methods for fabrication of hybrid perovskites-based optoelectronic devices, including PDs and solar cells.
