This research explores the wide range of potential applications of perovskite heterostructures (PHSs). Recently, researchers have made considerable progress in optoelectronic devices based on PHSs for energy-related and sensing applications. Here we begin by introducing the fundamental theory of PHS and focus on its optoelectronic properties. We focus on fabricating and characterizing advanced semiconducting heterostructure optoelectronics devices. The main objective of understanding their fundamental behavior is to tailor and improve their functionalities and empower different applications. Therefore, we propose the development of light management in photo detectors using the following scalable and cost-effective fabrication techniques:
(i) The design of nano electronic and optoelectronic devices based on the layering of inorganic and organic hybrid Perovskite CH3NH3PbBr3/Molybdenum disulfide MoS2 single crystal. We developed a new method for stacking the n-type MoS2 single crystal with p-type Perovskite CH3NH3PbBr3 single crystal in the vertical direction, which enabled us to form a van der Waals heterojunction p–n diode. This demonstrates good current-voltage rectifying behavior in the dark and under light illumination.
(ii) The use of inkjet-printed photo detectors using Graphene/Perovskite/Graphene (GPG) Heterostructures in the visible light region. This is achieved by fabricating a graphene/perovskite metal-semiconductor-metal (MSM) configuration through inkjet printing or by employing the hybrid approach (a combination of inkjet printing and transferred layers) as a high-gain visible light photo detector.
This research opens a new path in the light management of optoelectronic devices.
